ETHYL(4-N-ACYLAMINOPYRIDIN-3-YL)GLYOXYLATE AND 5-AZAISATIN AS NEW SYNTHONS FOR A ROUTE TO VARIOUS NEW POLYHETEROCYCLES

摘要

From 4-N-protected-aminopyridines which were functionalized at their 3-position, 5-azaisatin and equivalent synthons where obtained. Via the use of the Pfitzinger reaction, these compounds provided an easy route to new and various polyheterocyclic compounds. [References: 7]
