The first total synthesis of Manumycin A, as its (+)-enantiomer, is reported. The synthetic route features an asymmetric epoxidation (based on Wynberg's chiral phase transfer methodology) for the preparation of the key epoxyquinol nucleus, and a further demonstration of the utility of the Stille reaction for the construction of the Manumycin lower side chain. This synthesis of Manumycin A corrects

The development of a general synthetic route to the manumycin family of antibiotics is described and exemplified by the first total synthesis of alisamycin in racemic form.

A Stille palladium catalysed vinyl halide-vinyl stannane or aryl stannane coupling approach to the title compounds is described. The 2-aminocyclopentanedione-derived vinyl bromides (12, n = 1, 2, 3) were prepared and coupled to synthesise 2880-II (4), a Streptomyces metabolite, asuka-mABA (6), obtained during investigations to elucidate the biogenesis of the antibiotic asukamycin, and limocrocin (10), a naturally occurring antibiotic and antiviral agent.
