Heterocyclization of vic-substituted hydroxamic acid salts of acetylenyl-pyrazoles: A new procedure for the preparation of pyrazolo[3,4-c]pyridin-7-ones

Abstract

Procedures for the preparation of 5-substituted pyrazolo[3,4-c]pyridin-7-ones and 5-substituted 6-hydroxypyrazolo[3,4-c]pyridin-7-ones have been developed based on heterocyclization of vic-acetylenylpyrazolylhydroxamic acids under the influence of copper(I) salts in dimethylformamide or with organic bases in butanol or methanol.
