摘要
Addition of organocuprates, generated in situ using an excess of a 1:2 mixture of CuI center dot DMS and Grignard reagent, to N-enoyl oxazolidinethiones in the presence of excess TMSI gave preferentially the anti diastereomer where the addition took place when the conformation of the substrate was syn-s-cis. The reaction was investigated with indene-based and three different phenyl glycine derived oxazolidinethiones.
