2-Acyl-1,3-dithiane 1-oxides undergo diastereoselectiveaddition of Grignardreagents; the degree of selectivity observed is highly dependent upon the solvent and the halide counter-ion used; very high selectivities have been observed under certain reaction conditions.
The first total synthesis of (-)-aurafuron A is presented. It features a Suzuki cross-coupling reaction and a high yielding anionic aldol addition as central carbon skeleton building reactions. The synthesis confirms the proposed structure including its configuration and allows for detailed SAR studies.
