Diastereoselective carbon-carbon bond forming reaction of 2,3-O-isopropylidene-D (and L)-glyceraldehydes (D and L-2) with ketene silyl acetals (la,b) occurred in acetonitrile under mild conditions to give the-corresponding anti-P-siloxyesters (D and L-3a) as major products, which could be converted
