SYNTHESIS OF AZOLOYL KETONE AND AZOLOYLACETIC ACID DERIVATIVES: REACTIONS OF 4-ARYLAZO-2-OXAZOLIN-5-ONES WITH ACTIVE METHYLENE COMPOUNDS

The rearrangement of 4-arylazo-2-oxazolin-5-ones (1) with active methylene compounds was investigated.The 1,2,4-triazolyl derivatives (11) could be obtained on treatment of 1 with 2-pyrazolin-5-one derivatives.The behaviour of the synthesized derivatives

Activated Nitriles in Heterocyclic Synthesis. A Novel Synthesis of 1,2,4-Triazol-3-oyl Nitriles

Synthesis of 1,2,4-triazoloyl nitriles via reaction of 4-phenylhydrazono-2-phenyl-2-oxazolin-5-one and 4-phenylhydrazono-2-ethoxy-2-thiazolin-5-one with active methylene nitriles was accomplished.Some of the chemical properties of the nitriles obtained are reported.
