Seventeen years after the isolation of the promising antitumor antibiotic fredericamycin A, the first asymmetric total synthesis of this compound has been accomplished and thereby its absolute configuration established. The key feature is the regiocontrolled [4+2] cycloaddition of 3 to 2, which was obtained by the stereospecific rearrangement of 1. Cp = (-)-camphanoyl.
分离出有前途的抗肿瘤抗生素腓特烈霉素A十七年后,该化合物首次完成了不对称全合成,从而确定了其绝对构型。关键特征是区域控制的3至2的[4 + 2]环加成反应,这是通过1的立体特异性重排获得的。Cp=(-)-樟脑酰基。
