Synthesis and structure–activity relationship study of FD-891: importance of the side chain and C8–C9 epoxide for cytotoxic activity against cancer cells
Unified synthesis of FD-891 analogs and their structure-activityrelationship are described. By using stereoselective allylation/crotylation and Evans aldol chemistry, six side-chain fragments having different length and terminus were synthesized. These fragments were coupled with a macrolactone fragment, improved synthesis of which was also developed here, to generate FD-891 and five truncated analogs

A total synthesis of the naturally occurring, cytotoxic macrolide FD-891 is described. Three fragments were first stereoselectively constructed using mainly asymmetric aldol and allylation reactions. The complete framework was then assembled using two Julia-Kocienski olefinations to connect the three fragments and a Yamaguchi reaction to close the macrolactone ring.
