Enantioselective construction of 2-(cyclohex-2-enyl)phenols from chiral equivalents of cyclohex-2-enols has been investigated by employing a concurrent retro-Diels-Alder reaction and Claisen rearrangement protocol. Utilizing the enantiomerically pure product obtained, the first enantiocontrolled synthesis of a phenolic natural sesquiterpene (+)-curcudiol, isolated from the marine sponge Didiscus flavus, has been demonstrated.
通过同时采用逆 Diels-Alder 反应和克莱森重排协议,研究了从环己-2-烯醇的手性等价物生成 2-(环己-2-烯基)
