Unsaturated amides derived from 2-amino-3-hydroxycyclopentenone: A stille approach to the synthesis of asuka-mABA, 2880-II, and limocrocin
摘要:
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.
