摘要
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.
