Reaction of Nitrilimines with Aromatic and Heterocyclic Ketoximes, Part 3: Synthesis of Substituted 1, 2, 4-Triazoles and 1, 2, 4, 8-Tetraazaspiro [4, 5] dec-2-enes

Abstract

Nitrilimines (Za-g) react with acetophenone oxime (3) to afford 3—acyl-1-aryl-4, 5-dihydro-S-methyl-S-phenyl-1H-1, 2, 4-triazoles (4a—g). Similarly, the reaction of nitrilimines (2) with 1-methy1-4—piperidone oxime (6) gives 3-acyl-1-aryl-8-methyl-1, 2, 4, 8—tetraazaspiro [4, 5] dec-2-enes (7). Spectral data of the title compounds are discussed.
