Convenient synthesis of 4-amino-3,5-disubstituted pyrazoles in one step from the corresponding diketo oximes

A convenient one-step protocol for the synthesis of 4-amino-3,5- disubstituted pyrazoles has been developed. This method employs readily available diketo oximes as starting materials, and employs hydrazine hydrate for the cyclization and subsequent reduct

Studies in nitrosopyrazoles. Part 1. Preparative and spectroscopic studies of some 3,5-dialkyl-4-nitrosopyrazoles

The preparations of a number of 3,5-disubstituted- and 1,3,5-trisubstituted-4-nitrosopyrazoles are described and a range of physical properties of these compounds are measured. Comparison is made with some 2,6-disubstituted nitrosobenzenes and it is shown from 13C NMR spectroscopy that the effects of substitution by flanking tert-butyl groups are moderated in the case of the pyrazoles from those in the aromatic C6 ring due to a lessening of steric hindrance. It is also suggested that steric effects are evident in the preparation of 1,3,5-substituted-4-nitrosopyrazoles when one of the flanking groups to the NO is tert-butyl or phenyl, there being no such effect for the corresponding case of the isobutyl group.
