Synthesis and tranformations of trinitroethyl esters of pyrazoline-carboxylic acids

  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

Abstract

Trinitroethyl esters of pyrazolinecarboxylic acids were synthesized by the reaction of trinitroethyl sters of unsaturated carboxylic acids with diazomethane. The reaction is stereospecific. The trinitroethyl esters of pyrazolecarboxylic acids and N-acyl derivatives of pyrazolines were isolated during a study of the chemical properties of the compounds obtained.
