The C=C Bond Decomposition Initiated by Enamine-Azide Cycloaddition for Catalyst- and Additive-Free Synthesis of N-Sulfonyl Amidines

The chemo-selective synthesis of N-sulfonyl amidines is realized via the decomposition of the enamine C=C bond of enaminoesters through an in situ generated triazoline intermediate. Control experiments prove that the electron withdrawing ester group in the enamine component is crucial in inducing the chemo-selective formation of amidines. The method is featured with high efficiency and sustainability by employing pure water as medium without requiring any catalyst or additive.
