An Expedient Synthesis of Regioisomeric Pyrazole-Fused Cycloalkanones

Abstract Described herein is a novel one-pot procedure for the synthesis of pyrazoles through the in situ generation of a monohydrazone of cyclic 1,3-diones and subsequent cyclization with N,N-dimethylformamide dimethyl acetal. This route provides pyrazoles that have limited accessibility by other m...

Summary:Abstract Described herein is a novel one-pot procedure for the synthesis of pyrazoles through the in situ generation of a monohydrazone of cyclic 1,3-diones and subsequent cyclization with N,N-dimethylformamide dimethyl acetal. This route provides pyrazoles that have limited accessibility by other methods.
