摘要
An efficient general synthetic approach giving the possibility of a facile access to a wide range of novel 1,2,3-triazole bridge-connected phosphonate derivatives of coumarin, based on a copper(I)-catalyzed azide-alkyne 1,3-dipolar cycloaddition, has been developed. Under the optimized conditions, a novel series of 1,2,3-triazole bridge-connected phosphonate derivatives of coumarin was synthesized in high yields, and their structures were elucidated by NMR, IR, and HR MS.
