[structure: see text] 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).
