A total, stereoselective synthesis of the cytotoxicmacrolideaspergillideB has been performed. A cross metathesis and a C-glycosidation via a Mukaiyama-type aldol reaction were key features of the synthesis. The macrocyclic lactone ring was created by means of the Yamaguchi procedure.

Total, stereoselective syntheses of the naturally occurring, cytotoxicmacrolidesaspergillide A and B are described. Olefin metatheses and asymmetric allylations were key steps in the synthetic sequences. Cytotoxicity assays against several tumor cell lines have been performed for the two aspergillides and some of the intermediates or side products of the synthetic sequence. One of these intermediates
