Boron-Directed Regio- and Stereoselective Enyne Cross Metathesis: Efficient Synthesis of Vinyl Boronate Containing 1,3-Dienes
摘要:
Regio- and stereoselective enyne cross metathesis reactions between borylated alkynes and terminal alkenes were realized to provide a variety of functionalized vinyl boronates. High chemical yield and regioselectivity was achieved irrespective of substituents on the alkyne and alkene counterparts, whereas Z/E-selectivity was found to be dependent upon the substituents both on the alkyne and alkene.
