The convergent, highly enantioselectivesynthesis of rhizoxin D, a natural product possessing potent antitumor and antifungal bioactivity, is described. The C(1)-C(9) fragment of the molecule was synthesized utilizing a threefold pseudosymmetric intermediate ultimately derived from gamma-butyrolactone. The central core of rhizoxin D was prepared via a chiral resolution/asymmetric aldol protocol. Several

A concise synthetic approach to the C(1) C(9) fragment of the antitumor macrolide rhizoxin via a three-fold pseudosymmetric intermediate is described. The preparation (from readily available gamma-butyrolactone) includes both an asymmetric allylation and an asymmetric aldol addition. The pseudosymmetry proved useful in the realization of the target (4).
