The total syntheses of (+)-inthomycin A, (+)-inthomycin B and (−)-inthomycin C, the oxazole-triene antibiotics isolated from Streptomyces sp., have been accomplished via the highly enantio- and stereoselective construction of the C1–C7 (iododienyl)aldol units by taking advantage of a Cinchona alkaloid-catalyzed asymmetric β-lactone synthesis and their isomerisation-free Stille coupling with (E)-5-
分离自链霉菌属的恶唑三烯类抗生素-(+)-ththomycin A,(+)-ththomycin B和(-)-ththomycin C的总合成是通过C1的高度对映体和立体选择性构建而完成的利用金鸡纳生物碱催化的不对称β-内酯合成及其无异构化的Stille偶联,可合成–C7(碘二烯基)醛醇单元(E)-5-(3-(三丁基锡烷基)烯丙基)恶唑。
