ENANTIOSELECTIVE SYNTHESIS OF THE C(18)-C(35) SEGMENT OF IMMUNOSUPPRESSANT FK-506 USING EFFICIENT NEW METHODOLOGY

A simple, enantiocontrolled and efficient route to an intermediate containing carbons 18 to 35 of the macrocyclic immunosuppressant FK-506 (1) is described which depends on a sequence of three enantioselective C-C bond forming reactions.
