摘要:
The first asymmetric total synthesis of (+)-3-(Z)-dihydrorhodophytin (1) has been accomplished in 15 steps in 17% overall yield from readily available starting material 6 in a substrate-controlled manner. Key steps in our synthesis are a highly stereoselective dianion alkylation for the synthesis of the alpha,alpha'-anti-RCM substrate and a strategy for the introduction of the chlorine function.
