Generation of 3-Carbanion Species from 3-Phenylsulfinyl- and 3-Phenylsulfonyl Propionic Acids

Kiyoshi Iwai; Hiroshi Kosugi; Akio Miyazaki; Hisashi Uda

Abstract During the course of studies on butenolide synthesis1 we have investigated the utilities of 3-sulfur-functionalized propionic acid derivatives. We report the results with 3-carbanion species obtained from 3-phenylsulfiny1- and 3-phenylsulfonylpropionic acids (1) and (2). These compounds were easily prepared from 3-phenylthiopropionic acid.
