摘要

Abstract A domino three-component reaction of 2-(2′, 3′-allenyl) acylacetates with aryl or alkenyl halides and aryl-or benzylamines afforded 4, 5-dihydro-1H-pyrrole derivatives highly chemo-and regioselectively in one pot through imine formation/imine-enamine tautomerization under the catalysis of palladium (0) and toluenesulfonic acid monohydrate. A high diastereoselectivity was observed.
