[GRAPHICS]Total synthesis of the immunosuppresant pironetin has been achieved by a synthetic route in which the connections between starting materials and the desired structure are readily discerned, Key steps include a diastereoselective Lewis acid mediated crotylstannane aldehyde addition, a highly selective Lewis acid promoted Mukaiyama aldol reaction, an anti-selective Sml(2) reduction of a beta -hydroxyketone, and finally a lactone annulation reaction.
