Primary amidations of carboxylic acids 1 or 3 with NH4Cl in the presence of ClCO2Et and Et3N were developed to afford the corresponding primary amides in 22% to quantitative yields. Additionally, we have applied the amidation to the preparation of various amides containing hydroxamic acids and achieved the synthesis of (1S,2R)-tranylcypromine as an antidepressant medicine via Lossen rearrangement.
Stereoselectivity and regioselectivity in nucleophilic ring opening in derivatives of 3-phenylisoxazolo[2,3-a]pyrimidine. Unpredicted dimerization and ring transformation. Syntheses of derivatives of pyrimidinylmethylamine, pyrimidinylmethylamino acid ami

The nucleophilic ring opening of the isoxazolone ring in 2-oxo-3-phenylisoxazolo[2,3-a]pyrimidine derivatives by optically active amino acid amides and ephedrine led to pyrimidinylmethylamino acid amides. Using amides of different L-amino acids and (-)-ep
