A NEW SYNTHESIS OF 3,5-DISUBSTITUTED PYRAZOLES BY REACTION OF α,γ-DIPYROLIDINYLGLUTARONITRILES (MASKED α,γ-DIKETONE EQUIVALENTS) WITH HYDRAZINES
An efficient sequence proposed for a new synthetic method of 3,5-disubstituted pyrazoles involves the reaction of α,γ-dipyrolidinylglutaronitriles (masked α,γ-diketone equivalents) with hydrazines.
