Some Transformations of Tertiary N-Furfurylamides of Aromatic and Heteroaromatic Carboxylic Acids under Acidic Conditions

Abstract

Acid-catalyzed transformations of tertiary N-furfuryl­amides of ortho-amino substituted aromatic and heteroaromatic carboxylic acids accompanied by elimination of the furfuryl moiety are investigated.

N-furfurylamides - elimination - ring opening - pyrrolo[1,2-a]diazepines
