Abstract
A series of dihydropyrazolo[3,4-b]pyridin-6-ones 3 was prepared by cyclization of 5-amino-1-aryl-3-emthylpyrazoles 1 and Meldrum's acid benzylidene derivatives 2 in nitrobenzene. The structure of 4,5- dihydropyrazolo[3,4-b]pyridin-6-ones and reaction orientation were determined by nmr measurement.
