Abstract
Abstract The reduction of α-keto esters derived from (1 l )-1,2;5,6-biscyclohexylidene-3- tert -butyldimethysilyl- chiro -inositol with Selectride ® proceeded with high diastereoselectivity to afford the corresponding α-hydroxy esters. Addition of 18-Crown-6 led to dramatic changeover in diastereofacial selectivity.
