Published: May 2009

AbstractBackground Questions about the international reliability and validity of aspects of psychopathy have been raised for adults, but hardly considered when applying the constructs to children.Aims/objectives Our aim was to compare the psychometrics of a new instrument to measure psychopathic traits in children between two countries – the Netherlands and Greece. We also tested the hypothesis that, in both countries, both narcissistic‐egocentric and callous‐unemotional dimensions would be related to observed behavioural disorders.Methods The Social and Emotional Detachment Questionnaire was used to assess narcissistic‐egocentric and callous‐unemotional dimensions of personality in representative national and community samples of 4–12‐year‐old children in the Netherlands and Greece, respectively. Parents filled in the questionnaires anonymously and also provided ratings of conduct disorders.Results A two‐dimensional construct of the psychopathic syndrome depicting, respectively, narcissistic and unemotional traits was reliable and valid in both countries, although there was considerable correlation between these two dimensions, which we designated ‘social detachment’ and ‘emotional detachment’, respectively. In both countries, the composite of social and emotional detachment was associated with aggressive and antisocial conduct disorders.Conclusions/implications The reliability, validity and predictive value of this questionnaire must be tested further, for example, through multiple informants and longitudinally, but our findings that the tool performs robustly in two very different European countries is encouraging in terms of its potential value as a clinical screening tool and a tool for furthering the understanding of serious behavioural disorders in children.

AbstractCaught in the net: Zirconia‐modified SBA‐15 mesoporous silica with a specific 3D net‐linked morphology (see picture) is prepared by using a facile method. This new functional material can trap particles in tobacco smoke and so can be applied towards environmental protection.magnified imageA novel, versatile functional mesoporous material with the structure of SBA‐15 but a specific 3D net‐linked morphology has been prepared by using a facile method. This material has been assessed for its ability to reduce the level of nitrosamines in tobacco smoke so that the actual effect of this material in the reduction of carcinogenic environmental pollutants in a complex chemical system can be verified. By adjusting the force field during the hydrolysis and condensation processes of tetramethyl orthosilicate (TMOS) in an aqueous reaction system, the SBA‐15 silica, which has a special morphology in that it is long and fiberlike from a microscopic view but large and block‐like from a macroscopic angle, has been successfully synthesized. Moreover, the synthetic product is no longer a powder but a block because of its specific 3D net‐linked morphology, which enables the material not only to trap particles in smoke but also to potentially be applied as a device. To strengthen the adsorptive capability of this porous material, a dry‐impregnation procedure was applied in which zirconia was coated on the silica wall without changing the morphology. As expected, this functional material shows a high activity in the adsorption of N′‐nitrosonornicotine (NNN), a bulky tobacco‐specific nitrosamine, in solution and of N‐nitrosopyrrolidine (NPYR), a volatile nitrosamine, in the gas stream. Furthermore, this 3D net‐linked SBA‐15 material can efficiently decrease the amount of nitrosamines and total number of particles in mainstream smoke when it is tested as an additive in the filter of a cigarette, thus providing powerful protection for the environment and public health.

AbstractOoh Betti! A new diastereoselective synthesis of α‐aminophosphonates has been developed based on the reaction of trialkyl phosphites with chiral imines derived from (R)‐ or (S)‐1‐(α‐aminobenzyl)‐2‐naphthol (Betti base; see scheme, X=H, CH3, or Br). The reaction proceeds with high diastereoselectivity. Treatment with HCl results in the formation of the desired α‐aminophosphonic acids.magnified imageA new diastereoselective synthesis of α‐aminophosphonates has been developed, based on the reaction, in the presence of trifluoroacetic acid, of trialkyl phosphites with chiral imines derived from (R)‐ or (S)‐1‐(α‐aminobenzyl)‐2‐naphthol. The reaction proceeds at room temperature in toluene with high diastereoselectivity. The major diastereomer can be separated by crystallization from an appropriate solvent. The relative configuration of both chiral centers of the major diastereomer was determined by single‐crystal X‐ray structure analysis. The desired α‐aminophosphonic acids can be obtained in enantiopure form by treatment of the corresponding diastereomers with HCl.
Cd13−xInySb10 (x≈2.7, y≈1.5): An Interstitial‐Free Variant of Thermoelectric β‐Zn4Sb3

AbstractAlthough free from structural disorder, the new intermetallic compound Cd13−xInySb10 (see figure) displays similarly low thermal conductivity values as disordered thermoelectric β‐Zn4Sb3 with an isostructural framework.magnified imageCd13−xInySb10 (x≈2.7, y≈1.5) was synthesized in the form of mm‐sized crystals from reaction mixtures containing excess cadmium. The intermetallic compound crystallizes in the rhombohedral space group R$\bar 3$m with a=12.9704(4), c=12.9443(5) Å, V=1886.0(1) Å3, Z=3 and is isostructural to thermoelectric β‐Zn4Sb3 and β‐Cd4Sb3. However, in contrast to these last two compounds Cd13−xInySb10 is free from interstitial atoms and does not display any temperature polymorphism. The electrical resistivity of Cd13−xInySb10 is considerably higher than that of Zn4Sb3 and Cd4Sb3 although the temperature behavior remains that of a metal. The thermal conductivity of Cd13−xInySb10 is low, with room‐temperature magnitudes around 0.8 W m−1 K−1, which is comparable to disordered or complex structured Cd4Sb3 and Zn4Sb3.
A Designer Axially Chiral Amino Sulfonamide as an Efficient Organocatalyst for Direct Asymmetric anti‐Selective Mannich Reactions and syn‐Selective Cross‐Aldol Reactions
Authors: Kano Taichi , Yamaguchi Yukako , Maruoka Keiji 
Published: May 2009

AbstractAmino sulfonamide catalyst: A distal proton of the axially chiral amino sulfonamide (S)‐1 realized the opposite diastereoselectivity in Mannich and cross‐aldol reactions compared with that observed in proline‐catalyzed reactions. The reactions catalyzed by (S)‐1 proceeded smoothly to give the anti‐Mannich and syn‐aldol adducts in excellent enantioselectivity (see scheme).magnified imageA direct asymmetric Mannich reaction using a novel axially chiral amino sulfonamide (S)‐3 that is highly anti‐ and enantioselective has been developed. For instance, in the presence of a catalytic amount of (S)‐3, the reactions between aldehydes and α‐imino esters proceeded smoothly to give anti Mannich products with a significantly higher anti/syn ratio and enantioselectivity than previously possible. By utilizing N‐Boc‐protected aromatic imines instead of α‐imino esters, the synthetically useful Boc protecting group and various aromatic or heteroaromatic substituents were installed into the anti Mannich products and consequently the substrate scope of the anti‐selective Mannich reaction and the synthetic utility of the anti Mannich products have been expanded. The axially chiral amino sulfonamide (S)‐3 has also been successfully applied to asymmetric direct cross‐aldol reaction between two different aldehydes. The catalyst (S)‐3 has the advantage of giving mainly syn products, whereas proline shows the opposite anti selectivity.

AbstractHighly effective: We report herein the first and highly efficient total syntheses of norzoanthamine and zoanthamine in full detail, which involves stereoselective synthesis of the requisite triene for an intramolecular Diels–Alder reaction via three‐component coupling reactions, the intramolecular Diels–Alder reaction, and subsequent crucial bis‐aminoacetalization as the key steps.magnified imageThe zoanthamine alkaloids, a type of heptacyclic marine alkaloid isolated from colonial zoanthids of the genus Zoanthus sp., have distinctive biological and pharmacological properties in addition to their unique chemical structures with stereochemical complexity. Namely, norzoanthamine (1) can suppress the loss of bone weight and strength in ovariectomized mice and has been expected as a promising candidate for a new type of antiosteoporotic drug, while zoanthamine (2) has exhibited potent inhibitory activity toward phorbol myristate‐induced inflammation in addition to powerful analgesic effects. Recently, norzoanthamine derivatives were demonstrated to inhibit strongly the growth of P‐388 murine leukemia cell lines, in addition to their potent antiplatelet activities on human platelet aggregation. Their distinctive biological properties, combined with novel chemical structures, make this family of alkaloids extremely attractive targets for chemical synthesis. However, the chemical synthesis of the zoanthamine alkaloids has been impeded owing to their densely functionalized complex stereostructures. In this paper, we report the first and highly efficient total syntheses of norzoanthamine (1) and zoanthamine (2) in full detail, which involve stereoselective synthesis of the requisite triene (18) for an intramolecular Diels–Alder reaction via the sequential three‐component coupling reactions, the key intramolecular Diels–Alder reaction, and subsequent crucial bis‐aminoacetalization as the key steps. Ultimately, we achieved the total synthesis of norzoanthamine (1) in 41 steps with an overall yield of 3.5 % (an average of 92 % yield each step) and that of zoanthamine (2) in 43 steps with an overall yield of 2.2 % (an average of 91 % yield each step) starting from (R)‐5‐methylcyclohexenone (3), respectively.
