Abstract
A modification of the Gassman oxindole synthesis is described that pro ceeds from anilines and ethyl (methylsulfinyl)acelate, using oxalyl ch loride to activate the sulfoxide to facilitate the formation of the ke y N - S bonded intermediate. This procedure is particularly convenient for reactions carried out on smaller scales and for anilines that are susceptible to electrophilic halogenation. Copyright (C) 1996 Elsevie r Science Ltd
