A One-Pot Synthesis of Sulfonyl Amidinesvia Three-Component Reaction Under Mild and Solvent-Free Conditions

Publikováno v: Journal of Current Scientific Research. 1:1-12

A convenient one-pot synthetic protocol for the preparation of sulfonyl amidines has been developed. The procedure combines three-component reaction of sulfonyl azide, methyl propiolate and secondary cyclic amine coupling in one sequence without any
