The total synthesis of (+)-(6R,2′S)-cryptocaryalactone and (−)-(6S,2′S)-epi cryptocaryalactone is reported based on asymmetric acetate aldol reaction. Still–Gennari reaction, Evans acetal intramolecular oxa-Michael reaction and lactonisation are the key steps in the target synthesis.
基于不对称的乙酸羟醛醛醇缩合反应,报道了(+)-(6 R,2 'S)-隐芳内酯和(-)-(6 S,2 'S)-epi隐烯丙基内酯的总合成。Still–Gennari反应,Evans缩醛分子内氧杂-Michael反应和内酯化是目标合成的关键步骤。
