Heterocycles | 1991

Preparation of 1-hydroxyindole derivatives and a new route to 2-substituted indoles

Toshiya Kawasaki; Atsushi Kodama; Tokiko Nishida; Kazuhisa Shimizu; Masanori Somei

An easy handling method of 1-hydroxyindole is developed. Based on the method, preparation and reaction of 1-hydroxyindole derivatives are investigated. A new regioselective lithiation of 1-methoxyindole and its application for the synthesis of 2-substituted indoles are also reported

Heterocycles | 1992

The chemistry of 1-hydroxyindole derivatives : nucleophilic substitution reactions on indole nucleus

Masanori Somei; Toshiya Kawasaki; Yoshikazu Fukui; Fumio Yamada; Tetsuya Kobayashi; Harumi Aoyama; Daisuke Shinmyo

Nucleophilic substitution reactions were newly found to occur generally in the chemistry of 1-hydroxyindole derivatives. Its application to the synthesis of a phytoalexin, brassicanal A, is reported

Heterocycles | 1992

A simple synthesis of a phytoalexin, methoxybrassinin

Masanori Somei; Kensuke Kobayashi; Kazuhisa Shimizu; Toshiya Kawasaki

A simple and an alternative multi-gram scale synthetic method for methoxybrassinin is developed starting from indole-3-carboxaldehyde

Heterocycles | 1990

Rhe first total syntheses of 9-methoxycarbazole-3-carboxaldehyde and methoxybrassinin1 (the chemistry of 1-methoxyindole)

Toshiya Kawasaki; Masanori Somei

The first total syntheses of an alkaloid 9-methoxycarbazole-3-carboxaldehyde and a phytoalexin methoxybrassinin are reported

Heterocycles | 1989

A new and simple synthesis of 1-hydroxyindole derivatives

Masanori Somei; Toshiya Kawasaki

Heterocycles | 1989

Masanori Somei; Toshiya Kawasaki; Kazuhisa Shimizu; Yoshikazu Fukui; Toshiharu Ohta

Heterocycles | 1988

A simple synthesis of 7-substituted 1-acetyl-2,3-dihydroindoles

Masanori Somei; Toshiya Kawasaki; Toshiharu Ohta

Chemical & Pharmaceutical Bulletin | 1989
