Abstract
An efficient copper hydride (CuH)-catalyzed enyne-nitrile coupling reaction provides polysubstituted N-H pyrroles bearing a broad range of functional groups in good yields with high regioselectivity. The Cu-based catalyst promotes both the initial reductive coupling and subsequent cyclization steps.
