A novel enantioselective synthesis of 1, 3-dioxin-4-ones having a 2-hydroxylated alkyl group at the 6-position has been accomplished by chiral tartaric acid-derived acylborane-mediated aldol condensation of the silyl enol ether derived from 6-methyl-derivatives of 1, 3-dioxin-4-one with achiral aldehydes.
