摘要：

The chiral phosphoric acid catalyzed asymmetric [3 + 2] annulation of substituted 2-vinylindoles with azlactones has been established. This reaction represented a practical approach for the synthesis of structurally diverse pyrrolo[1,2-a]indoles with two vicinal stereocenters including one tetrasubstituted stereocenter in good yields and good stereoselectivities under mild conditions.
