This work has been carried out to investigate the utility of 6 - amino - 4 - (aryl) - 2 - thioxopyridine - 3 , 5 - dicarbonitrile for the synthesis of a variety of new heterocyclic systems such as 6 - \\\pyridine , pyrazolo[3 , 4 - b]pyridine , pyrazolo[4 ̀, 3 ̀: 5 , 6]pyrido[2 , 3 - d] - pyrimidine , 3 , 6 - bis\\\pyrazolo - [3 , 4 - b]pyridine , thieno[2 , 3 - b]pyridine , pyrido[3 ̀, 2 ̀: 4 , 5]thieno[3 , 2 - d] - pyrimidine , pyrido[2 , 3 - d]pyrimidine , 2 , 7 - bis[ (alkyl) thio]pyrido[2 , 3 - d] - pyrimidine , of potential biological activity



2 - S - Alkylpyridines 2 - Thioxopyridine - 3 5 - dicarbonitrile Dimroth rearrangement. Thieno[2 , 3 - b]pyridine
