  名称：

  Total Synthesis of 10-Deoxymethynolide, the Aglycon of the Macrolide Antibiotic 10-Deoxymethymycin

  摘要：

  A short and efficient total synthesis of 10-deoxymethynolide (2c), the aglycon of 10-deoxymethymycin (1c), has been accomplished in 16 steps and 12% overall yield from (S)-3-O-p-toluenesulfonyl-3-hydroxy-2-methylpropanal (15c). The synthesis features an expeditious preparation of (+)-5a, a synthetic equivalent of the Prelog-Djerassi lactonic acid, and the construction of a 12-membered lactone through an intramolecular Nozaki-Hiyama-Kishi coupling reaction.
