The first stereoselective total synthesis of (–)-synrotolide has been realized by two different approaches, both starting from (S)-ethyl lactate. Both strategies used stereo- and regioselective epoxide opening with a nucleophile, aldehyde alkyne coupling and ring-closing metathesis as key steps. Judicious choice of reagents (CeCl3·7H2O and H2SiF6) for the chemoselective removal of protecting groups
(-)-synrotolide 的第一个立体选择性全合成已通过两种不同的方法实现,均从 (S)-乳酸乙酯开始。这两种策略都使用立体和区域选择性环氧化物开环,亲核试剂、醛炔偶联和闭环复分解作为关键步骤。明智地选择用于化学选择性去除保护基团的试剂(CeCl3·7H2O 和 H2SiF6)递送目标分子。
