[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

Ruthenium-catalyzed Alder ene reactions between borylated alkynes and terminal alkenes give the corresponding beta,beta-disubstituted vinyl boronates with high selectivity for the branched isomer. The stereochemistry of the vinyl boronate moiety was the result of a formal trans addition of the
