The protected C(1) to C(15) segment of FK-506 has been prepared from D-glucose, glycolic and L-pipecolic acid. The novel, highly active immunosuppressive agent FK-506 (1) has attracted considerable attention.1 The biological potency as well as some unique structural features render this 23-membered
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. Research in our group has recently led to the development of n
