Facile Transformation of alpha,beta-Unsaturated Carboxylic Acids to Alkenylboronic Esters via Rhodium-catalyzed Decarbonylative Borylation of alpha,beta-Unsaturated Thioesters
A two-step transformation of alpha,beta-unsaturated carboxylic acids to alkenylboronic esters has been achieved via thioesterification of carboxylic acids followed by rhodium-catalyzed decarbonylative borylation of thioesters. The latter reaction proceeds under mild conditions with broad functional-group tolerance, rendering a wide range of alkenylboronic esters easily accessible.
