  Concise Total Synthesis of (+)-Brefeldin A:  A Combined β-Lactone/Cross-Metathesis-Based Strategy

  摘要：

  A highly convergent total synthesis of (+)-brefeldin A that relies on a diastereoselective, beta-lactone-based cyclopentane synthesis combined with complex cross-metathesis reactions is described. The utility of beta-lactones for natural product synthesis and the versatility of cross-metathesis in this context were demonstrated, including the tolerance of an epimerizable aldehyde and a beta-lactone.
