A microwave‐assisted highly efficient intermolecular C−H functionalization sequence has been developed to access substituted isoquinolones using α‐amino acid esters as a directing group. This methodology enables a wide range of N‐benzoyl α‐amino ester derivatives to react via a Ru‐catalysed C−H bond activation sequence, to form isoquinolones with moderate to excellent yields. As an additional advantage

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.
