Petasis reaction of activated quinoline and isoquinoline with various boronic acids

Petasis reactions of activated forms of quinolines and isoquinolines with electron sufficient boronic acids such as 2-benzofuranboronic acid, trans-2-phenylvinylboronic acid etc in DCM proceeded smoothly at room temperature to provide the corresponding dihydroquinolines and dihydroisoquinolines in good to high yields.
