Preparation and diagnosis of new picolinic acid derivatives

Abstract

In this study, a new series of heterocyclic rings derived from picolinic acid was prepared. The quaternary reaction of acid hydrazone with chloroacetyl chloride was intended to obtain the azitidine-2-on ring known as beta-lactam and the preparation of the seventh ring of acid hydrazone reaction with the anhydride and phthalic anhydride To obtain a 3.1-oxabine loop. The five-ring of the picolinic acid hydrazide reaction with CS2 was also destined to obtain a 4,3,1-oxadiazole-2-thaion ring. The new compounds were diagnosed using FT-IR techniques and resonance technique Nuclear Magnetic H-NMR and 13C-NMR.
