Authors: Hara Takao , Ohkatsu Yasukazu , Osa Tetsuo 
Published: July 2006

Abstract
The oxidation of cumene was carried out using metal polyphthalocyanine as a catalyst. The catalyst activated an oxygen molecule to form a phthalocyanine-O2 complex, which abstracted the tertiary hydrogen of cumene to initiate the reaction. The catalyst had no activities on the decomposition of cumene hydroperoxide, formed selectively in the oxidation of cumene. The influence of the addition of pyridine was discussed.

STEREOCHEMISTRY OF THE 2,4-DIMETHYL-1,3-DIOXOLAN-2-YL RADICAL
Authors: Kobayashi Shigero O , Simamura Osamu 
Published: July 2006

Abstract
The acetone-initiated photochemical addition of cis- or trans-2,4-dimethyl-1,3-dioxolane to methyl acrylate at −78°C leads to a mixture of geometrically isomeric methyl 3-(2,4-dimethyl-1,3-dioxolan-2-yl)propionates with partial retention of the original configuration of the starting dioxolane. This constitutes evidence for a pyramidal structure of the radical centre of 1,3-dioxolan-2-yl radicals involved as an intermediate in the photochemical addition.

EVIDENCE FOR THE HYDROPHOBIC INTERACTION IN PFEIFFER EFFECT OF TRIS(1,10-PHENANTHROLINE)ZINC(II)-l-STRYCHNINE SYSTEM
Authors: Miyoshi Katsuhiko , Sakata Koro , Yoneda Hayami 
Published: July 2006

Abstract
The addition of tetraalkylammonium bromides R4NBr(R = C2H5, n-C3H7 and n-C4H9) did not enhance Pfeiffer effect of [Zn(phen)3]2+-l-strychnine system in water, while (CH3)4NBr enhanced it like simple salts. This could be best interpreted by assuming that hydrophobic R4N+ ions interfere with hydrophobic interaction between [Zn(phen)3]2+ and strychnine cation (stryH+), by forming hydrophobic bonding with [Zn(phen)3]2+ and/or stryH+.

Published: July 2006

Abstract
Reactions of 3-substituted 2-nitrosoimino-2,3-dihydrobenzothiazoles (1) with phenyllithium and n-butyllithium gave S, N-disubstituted o-aminothiophenol (3) as major product due to direct attack at the sulfur atom of benzothiazoline ring while that with benzyllithium gave 2,2-dibenzyl compound (2) and bis(N-substituted o-aminophenyl) disulfide (5). These results present a striking contrast to those with Grignard reagents.

A NEW METHOD FOR PEPTIDE SYNTHESIS USING o-NITROPHENYLSULFENYL N-CARBOXY α-AMINO ACID ANHYDRIDES
Authors: Katakai Ryoichi , Oya Masanao 
Published: July 2006

Abstract
A New method for peptide synthesis using o-nitrophenylsulfenyl α-amino acid anhydrides (Nps-NCAs) is reported. The method involves the reaction of the Nps-NCA with an amino acid ester or a peptide ester to give a N-protected peptide ester by the Nps group. Some peptide derivatives have been easily prepared without racemization in very high yields by the new method. The advantages of this method may result from the rapid acylation of the amino group by the NCAs without formation of by-product.

Based upon the stoichiometry, the dipole–dipole interaction mechanism was suggested first in the 1,3-dipolar cycloaddition, which is not inconsistent with the stereochemical results hitherto reported.
