Highly efficient conversion of fused 2-amino-4-aryl-4H-chromene-3-carbonitriles into fused 2-oxo-4-aryl-2H-chromene-3-carbonitriles using Vilsmeier conditions
摘要:
A simple, mild, and highly efficient protocol for the synthesis of fused 2-oxo-4-aryl-2H-chromene-3-carbonitriles has been developed starting from fused 2-amino-4-aryl-4H-chromene-3-carbonitriles utilizing Vilsmeier conditions. (C) 2013 Elsevier Ltd. All rights reserved.
