Formation of novel 1,2,3,4-tetrasubstituted 3-pyrrolines via cyclisation of γ-halo-β-ketoesters with aromatic amines and aldehydes
摘要:
Cyclisation of gamma-halo-beta-ketoesters with aromatic amines and aldehydes in methanol gave novel polysubstituted 3-pyrroline derivatives. A plausible mechanism for the reaction has been proposed. The structures of 1,2,3,4-tetrasubstituted 3-pyrrolines were confirmed by NMR spectroscopy and X-ray crystallography. (C) 2011 Elsevier Ltd. All rights reserved.
