Using a one-pot Sharpless asymmetric epoxidation/regioselective epoxide ring-opening as a key step, the protecting-group-free total synthesis of goniothalesdiol A was accomplished in only three steps starting from commercially available trans-cinnamaldehyde in 55.1% overall yield. In 6 previously reported total syntheses, 6–11 steps were required.
使用一锅Sharpless不对称环氧化/区域选择性环氧化物开环作为关键步骤,从市售反式肉桂醛开始,仅需三步即可完成无保护基的菊芋二醇A的总合成,总收率达55.1%。在先前报告的6个总合成中,需要6-11个步骤。
