The first total synthesis of oxazolomycin A, a structurally novel oxazole polyene gamma-lactam/beta-lactone antibiotic, is described. Key features Include the stereocontrolled construction of the right-hand heterocyclic core by taking advantage of an In(III)-catalyzed Conia-ene type cyclization and the asymmetric synthesis of the left-hand segment starting with a Cinchona alkaloid-catalyzed cyclocondensation of an aldehyde with an acid chloride.
