efficient and simple synthetic protocol for the synthesis of a number methyl esters of 2-(N-hydroxycarbamimidoyl)benzoyl-substituted (S)-α-amino acids via subsequent coupling and hydroxyamination of 2-cyanobenzamide derivatives has been developed. Comparative analysis of three pseudopeptide series based on 2-cyano- and 2-amidoxime-substituted benzoic acid and its pyridine and pyrazine counterparts has

diversity-oriented access to isoxazolino and isoxazolo benzazepines is elaborated via a post-Ugi heteroannulation involving intramolecular 1,3-dipolar cycloadditionreaction of nitrile oxides with alkenes and alkynes. This sequence offers an interesting multicomponent entry to a library of isoxazolino and isoxazolo benzazepines under mild reaction conditions in good to excellent yields.
