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