Abstract
[GRAPHICS] Total synthesis of the immunosuppresant pironetin has been achieved by a sy nthetic route in which the connections between starting materials and the d esired structure are readily discerned, Key steps include a diastereoselect ive Lewis acid mediated crotylstannane aldehyde addition, a highly selectiv e Lewis acid promoted Mukaiyama aldol reaction, an anti-selective Sml(2) re duction of a beta -hydroxyketone, and finally a lactone annulation reaction .
