2,2-Dimethyl-1,3-oxathiane 3,3-dioxide: A γ-hydroxypropyl anion equivalent

The reaction of 4-lithio-2,2-dimethyl-1,3-oxathiane 3,3-dioxide with various electrophiles is presented. Acylation of the anion provided labile 4-acyl-2,2-dimethyl-1,3-oxathiane 3,3-dioxides which underwent desulfonation with silica gel to produce γ-hydroxy ketones with three carbon unit elongation. Thus, 4-lithio-2,2-dimethyl-1,3-oxathiane 3,3-dioxide was shown to be a useful synthetic equivalent of a γ-hydroxypropyl anion. Methyl esters proved to be the best acylating agents in this reaction. Synthetic utility of this carbon chain elongation was illustrated by the syntheses of dl-lanceol and dl-dihydrojasmone.
