  Total Synthesis of Basiliskamides A and B

  摘要：

  The first enantioselective synthesis of the polyketide antibiotics basiliskamides A and B, which exhibit potent in vivo activity against Candida albicans and Aspergillus fumigatus, has been achieved. Serial asymmetric crotylsilane and crotylboronate additions established the C7-C10 stereochemical tetrad. Takai iodoolefination and palladium-mediated cross-coupling were used to install the (Z,E)-vinyl acrylamide. Spectroscopic data is consistent with the assignment of the absolute configurations of the natural products as (7S,8S,9R,10S).

• Stereoselective synthesis of basiliskamides A and B via Prins cyclisation

  A stereoselective and convergent approach to basiliskamides A and B is achieved through our recently developed strategy for the construction of polyketide precursors via Prins cyclisation. The approach mainly relies upon reductive opening of 1-iodomethyl cyclic ethers, Mitsunobu inversion, Takai olefination and Stille coupling along with Prins cyclisation. (c) 2008 Elsevier Ltd.
