  Total synthesis of (+)-crocacin C

  摘要：

  Two approaches toward the total synthesis of cytotoxic polyketide natural product (+)-crocacin C (1) are described. The first approach, which was ultimately unsuccessful, was replaced altogether with a second that afforded target 1 in 10 linear steps from commercially available Evans' chiral propionimide (5% overall yield).
