Kondo, Yoshinori,Kojima, Satoshi,Sakamoto, Takao

, p. 2741 - 2746 (1996)

7-Substituted indoles were synthesized by the basic cyclization of 6-substituted tert-butyl 2-(trimethylsilyiethynyl)phenylcarbamates which were derived by the lithiation of tert-butyl 2- (trimethylsilylethynyl)phenylcarbamate and the subsequent reaction with electrophiles.
