The fungal polyketide derivative (-)-ACRL toxin IIIB (4) has been prepared in 15 steps (21 % yield) from ketone (S)-7 with 88% overall ds. The boron-mediated anti aldol reaction of (S)-7 is used twice in the synthesis, controlling the stereochemistry at C8 / C9 and C12 / C13.
真菌聚酮化合物衍生物(-)-ACRL毒素IIIB(4)由酮(S)-7分15个步骤(产率为21%)制备,总ds为88%。硼介导的(S)-7的抗醛醇缩合反应在合成中使用了两次,将立体化学控制在C 8 / C 9和C 12 / C 13处。
