摘要:
[GRAPHICS] The callipeltoside A chlorocyclopropyl-containing dienyne side chain has been synthesized in nine steps and 33% overall yield from commercially available 1,2,5,6-O-dicyclohexylidene-D-mannitol. The key steps in the synthesis are a highly diastereoselective cyclopropanation of a vinyl chloride allylic ether and a Suzuki cross-coupling to complete the carbon framework.
