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.

Yamaguchi reaction to close the macrolactone ring. Some specific biologicalproperties (cytotoxicity, binding to tubulin) have been determined for both macrolides. The E configuration of the C12-C13 olefinic bond seems to be an important feature in determining the cytotoxicity but the precise biological mechanism of the latter still remains to be cleared.
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
