The first total asymmetric synthesis and the attribution of the absolute configurations of (+)-dienomycin C (1), an alkaloid isolated from a Streptomyces strain, are reported. This compound was prepared in six steps from the enantiopure tricarbonyl(dienal)iron complex (+)-4 which is easily obtained by separating preformed diastereomers, starting from phenylpentadienoic acid and (S)-methyl mandelate
报道了从链霉菌属菌株中分离出的生物碱 (+)-双烯霉素 C (1) 的第一次完全不对称合成和绝对构型的归属。该化合物是从对映纯的三羰基(二烯醛)铁络合物 (+)-4 分六步制备的,该络合物很容易通过分离预先形成的非对映异构体而获得,从苯基戊二烯酸和 (S)-扁桃酸甲酯开始。
