  Stereoselective tandem synthesis of oxazolo-fused pyrroloquinolines from o-alkynylaldehydes via Ag(I)-catalyzed regioselective 5-exo-dig ring closure

  摘要：

  A tandem approach for the regio- and stereoselective synthesis of oxazolo-fused pyrroloquinolines 3a-I via the reaction of o-alkynylaldehydes 1a-i with chiral amino alcohols 2a-c under mild reaction conditions is described. The possible participation of the pyridine ring in the regioselective formation of 5-exo-dig cyclized products was supported by the controlled experiments. The structures and stereochemistry of the products were confirmed by NOESY and X-ray crystallographic studies. (C) 2014 Elsevier Ltd. All rights reserved.
