The alpha-dimethyl(1-phenylthio)cyclopropylsilyl group was used as a new ma
sked hydroxy group. Three procedures have been devised to allow the oxidati
on of this silicon group in the presence of various functionalities. The de
sired alcohols are obtained in high yields with retention of configuration
at the carbon centre. (C) 2000 Elsevier Science Ltd. All rights reserved.
