Abstract
We report in this paper the synthesis of 6-substituted pyrazolo[4,3-c] pyridin-4-ones, 6-substituted 5-hydroxypyrazolo[4,3-c]pyridin-6-ones, 5-substituted pyrazolo[3,4-c]pyridin-7-ones and 5-substituted 6-hydroxypyrazolo[3,4-c]pyridin-7-ones by heterocyclization of vic-acetylenylpyrazol-hydroxamic acids under the influence of copper(I) salt in dimethylformamide or with organic bases in butanol or methanol.
