  Enantioselective synthesis of peperomins A, C, D, and analogs — Examination of diastereoselective cuprate conjugate additions to <i>N</i>-enoyl-4-diphenylmethyl-2-oxazolidinones

  摘要：

  A concise and general route to secolignans has been developed. The first total synthesis of secolignans peperomin A (1a), peperomin C (1b), and peperomin D (1c) was accomplished in similar to 28% overall yield over five synthetic steps. Peperomin analogs (1d) and (1e), possessing two differentially substituted aryl groups, were synthesized by a highly selective conjugate addition. The overall yield for the analogs 1d and 1e were 27 and 26%, respectively.
