  The Synthesis and Microbiological Activity of 2-Mercapto-4-methoxypyridine-3-carbonitrile Derivatives

  摘要：

  Synthesis of 2-(3-cyano-4-methoxypyridin-2-ylthio)acetic acid derivatives, starting either from 2-bromo-4-methoxypyridine-3-carbonitrile or 2-mercapto-4-methoxypyridine-3-carbonitrile is reported. The obtained products could be transformed by intramolecular Thorpe-Ziegler cyclization to related thieno[2,3-b]pyridines. Diazotization of 3-amino-N-(4-chlorophenyl)-4-methoxythieno[2,3-b]pyridine-2-carboxamide resulted in formation of a suitable pyridothienotriazine derivative. Some of the prepared compounds demonstrated noticeable bacteriostatic or tuberculostatic activity.
