The Z-selective cross metathesis of allylic-substituted olefins is explored with recently developed ruthenium-based metathesis catalysts. The reaction proceeds with excellent stereoselectivity for the Z-isomer (typically >95%) and yields of up to 88% for a variety of allylic substituents. This includes the first synthesis of Z-alpha,beta-unsaturated acetals by cross metathesis and their elaboration
用最近开发的基于钌的复分解催化剂探索了烯丙基取代的烯烃的Z-选择性交叉复分解。该反应对Z-异构体具有出色的立体选择性(通常> 95%),并且对于多种烯丙基取代基的收率高达88%。这包括通过交叉复分解法首次合成Z-α,β-不饱和缩醛并将其精制为Z-α,β-不饱和醛。另外,该反应耐受各种交联伙伴,其功能和空间分布各不相同。
