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 allylicsubstituents. This includes the first synthesis of Z-alpha,beta-unsaturated acetals by cross metathesis and their elaboration
