Preparation and Reactions of 2,2-Dimethyl-1,3-dioxan-5-one-SAMP-Hydrazone: A Versatile Chiral Dihydroxyacetone Equivalent

Abstract

The SAMP-hydrazone of 2,2-dimethyl-1,3-dioxan-5-one represents a valuable chiral dihydroxyacetone equivalent. Asymmetric mono- or α,α′-bisalkylations followed by auxiliary cleavage leads to the corresponding mono- or α,α′-disubstituted, acetonide protected ketodiols in excellent diastereo- and enantiomeric excesses.

Key words

asymmetric synthesis - ketodiols - alkylations - hydrazones - chiral dihydroxyacetone equivalent
