  Efficient synthesis of the 6,6-spiroacetal of spirofungin A

  摘要：

  The 6,6-spiroacetal segment of spirofungin A, an antifungal antibiotic isolated from Streptomyces violaceusniger Tu 4113, was efficiently prepared via the coupling reaction of the Weinreb amide and the alkyne which are readily available from the common intermediate. The synthesis includes the unsymmetrization through a stereoinversion at the C11 position and the transacetalization as the key steps. (C) 2003 Elsevier Science Ltd. All rights reserved.
