Abstract

A short route to sulfones 9ac is described. These synthons encompassing a syn 1,3-diol motif are model compounds for the C16–C24 fragment of Dolabelides. The benzylidene protecting group can be reduced regioselectively to furnish β-hydroxysulfones 10ab. First attempts of Julia coupling of the dianions derived from these substrates with aldehydes and ketones are also reported.
