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 solvent or catalyst and at room temperature. The r…
