With the aim of finding a therapeutic agent for urolithiasis, forty-three new N-(aroyl)-glycinohydroxamic acid derivatives and related compounds were synthesized and examined for urease inhibitory activity. Their urinary excretion in rats was also determined.

An atom-economical method for accessing tetrasubstituted 4,5-biscarbonylimidazoles by reaction between glycine derivatives and 5-alkoxyoxazoles is reported. The method, which involves a copper-catalyzedaerobic oxidative [2 + 3] cyclization/aromatization cascade process, starts from readily available and inexpensive materials, uses molecular oxygen as a co-oxidant, and has a broad substrate scope.
