title: Boron-directed regio- and stereoselective enyne cross metathesis: efficient synthesis of vinyl boronate containing 1,3-dienes.
abstract: [reaction: see text] 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.
