文摘

The cross-coupling reaction of 2-(1-alkenyl)-1,3,2-benzodioxaboroles, obtained from alkynes and catecholborane, and other boron derivativeswith a lactam-derived N-Boc enol triflate occurred under very mild conditions in a THF-water medium employing (Ph₃P)₂PdCl₂ as a catalyst,providing the corresponding 6-substituted N-Boc 3,4-dihydro-2H-pyridines in high yields.
