Abstract

A general method for preparation of a variety of enantiomericdy pure 2-substituted glycerol derivatives 1 was developed by utilizing l-menthone as a chiral template. Spiroacetals 6 derived formally from 2-substituted 2-(trimethylsiloxy)-1, 3-propanediols and 1-menthone were prepared with high stereoselectivity (> 95% de) either by Grignard reactions of oxospiroacetal4 or by epoxidation of methylenespiroacetal5 followed by ring opening with ...
