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.
