AN ONE-POT SYNTHESIS OF 3-ALKYLINDOLES FROM o-TOLYL ISOCYANIDES
Authors: Ito Yoshihiko , Kobayashi Kazuhiro , Seko Norihiko , Saegusa Takeo 
Published: July 2006

Abstract
Indolyllithium arising from ring-closure of o-lithiomethylphenyl isocyanide, which is generated in situ by the reaction of o-tolyl isocyanide with lithium diisopropylamide in diglyme at −78°C, is treated with anhydrous MgI2 prior to alkylations with alkyl halides to give 3-alkylindoles selectively in moderate to excellent yields. The reaction provides a convenient method for synthesis of 3-alkylindoles starting with o-tolyl isocyanide.

Abstract

ACETOXYSELENATION: REACTION OF OLEFINS WITH DIPHENYL DISELENIDE AND CUPRIC ACETATE
Authors: Miyoshi Noritaka , Ohno Yutaka , Kondo Kiyoshi , Murai Shinji , Sonoda Noboru 
Published: July 2006

Abstract
In the presence of cupric acetate, diphenyl diselenide was found to react with olefins in acetic acid to afford 2-acetoxyalkyl phenyl selenide (1). The similar reaction proceeded by use of a catalytic amount of cupric acetate in the presence of oxygen. Formation of benzeneselenenyl acetate(PhSeOAc) as an intermediate is suggested.

Microbial oxidation of 2-methylpropane-1,3-diol (1a) proceeded with distinction of pro-(R) and pro-(S) hydroxymethyl groups resulting in the formation of β-hydroxyisobutyric acid (2a) of high optical purity. 2-Ethyl and 2-isopropyl derivatives (1b, c) were also oxidized to give the corresponding hydroxy acids (2b, c), but the optical yields were low.
LINE SHAPE BEHAVIOR OF THE RESONANCE CARS IN Zn-TETRAPHENYLPORPHIN
Authors: Adachi Yukio , Igarashi Ryosaku , Maeda Shiro 
Published: July 2006

Abstract
CARS of fluorescent Zn-tetraphenylporphin has been measured by ω1 radiations in resonance with the first allowed transition near 600nm. An appreciably resonant line was observed at 1360cm−1 and the line shape changed remarkably by moving ω1 within the absorbing region. The line shape behavior has been reasonably interpreted by picking out a doubly resonant term in the susceptibility expression, in which ω1 and ω3 are resonant with the 0–0 and 0–1 transitions respectively.

Authors: Kohata Kunio , Fukuyama Tsutomu , Kuchitsu Kozo 
Published: July 2006

Abstract
An electron diffraction study has shown that the inner–outer conformer of 1,2-dimethylhydrazine, the C–N–N–C dihedral angle being estimated to be about 90°, is a major conformer in the gas phase. Another conformer is found to have a smaller dihedral angle (inner–inner form). The thermal-average bond distances and angles of the inner–outer conformer have been determined.
SYNTHESES OF SYN- AND ANTI-[3.3](1,4)NAPHTHALENOPHANE AND INTRAMOLECULAR CYCLOADDITION PRODUCTS OF SYN- AND ANTI-[3.3](1,4)NAPHTHALENOPHANE DERIVATIVES
Authors: Kawabata Takeo , Shinmyozu Teruo , Inazu Takahiko , Yoshino Tamotsu 
Published: July 2006

Abstract
Two isomeric [3.3](1,4)naphthalenophanes, syn and anti (8 and 9), were synthesized. The absorption maxima 237 and 330 nm for 8, as well as 231, 241, and 325 nm for 9 may be ascribed to the transannular π-electronic interaction between two naphthalene moieties. On irradiation, syn- and anti-[3.3](1,4)naphthalenophane derivatives were transformed to the photoisomers (10 and 11) which were reconverted to the original compounds (2 and 3) when heated in the solid phase at 175°C.

Authors: Minami Ryuichi , Fueno Takayuki 
Published: July 2006

Authors: Asai Takeshi , Kiriyama Hideko 
Published: July 2006

Abstract
The phase transition of (NH4)2PdCl4 was confirmed at 132 K by the proton T1. A thermal hysteresis in T1 was observed, indicating that the transition is of a first-order. The transition is probably accompanied by the order–disorder change of an ammonium ion, but this is not effective for the transition temperature.

Authors: Tamaki Takashi 
Published: July 2006

Abstract
Intramolecular fluorescence quenching of 1-naphthylacetic acid derivatives has been interpreted in terms of electron transfer from the excited state of the naphthyl ring to the acyl group. Remarkable fluorescence quenching of the acyl chloride is attributable to successive deactivation of the excitation energy through the photocleavage of the C–Cl bond.

Authors: Sakiyama Fumio , Nakazawa Takashi 
Published: July 2006

Abstract
A new method for conversion of 3-alkylindoles to 3-alkyl-2-amino-3H-indol-3-ols is described. In this reaction, the indole nucleus was first oxidized with ozone to alkyl 2-formamidophenyl ketone, which was subsequently subjected to the reaction with cyanide ion in weakly alkaline medium to cyclize to the 3H-indole ring. The overall yield of the reaction was approximately 75 %. By this method an ionizable amidine function was introduced at the side chain of tryptophan.

Published: July 2006

Abstract
Stereoisomers of bis(crown ether)s were synthesized from meso- or dl-α,α′-dimethylglutaric acid and maleic or fumaric acid. Preliminary solvent extraction data suggested that the maleate derivative(cis form) differs considerably in the cation-complexing ability from the fumarate derivative(trans form), while two isomers of α,α′-dimethylglutarate derivatives are almost the same.

This method made it possible to determine 0.04ppm of mercury.

Authors: Kosaki Yukio , Miyamoto Akira , Murakami Yuichi 
Published: July 2006

Abstract
The selectivity to NH3 in the NO–H2 reaction on Pt/Al2O3 has been markedly decreased by the addition of metal oxides. This effect has been found to be brought by the hydrogen spillover from Pt to metal oxides, and by a successive reaction of NH3(the NO–NH3 reaction) as an intermediate of the NO–H2 reaction.
