recently discovered a novel reaction between iminosydnones and strained alkynes leading to two products resulting from ligation and fragmentation of iminosydnones under physiological conditions. We now report the synthesis of a panel of substituted iminosydnones and the structure reactivity relationship between these compounds and strained alkyne partners. This study identified the most relevant substituents

In a ''one-pot'' process, a variety of 3-alkyl and 3-aryl sydnoneimine hydrochlorides can be prepared in high yield, under mild conditions, by nitrosation of the corresponding aminoacetonitrile with isoamyl nitrite in diethyl ether followed by cyclization with HCl gas.
