Synthesis of 1,8‐Naphthyridine‐4(1H)‐one Sulfonamides by Thermolysis of 2‐Aminopyridinemethylene (Meldrum's Acid) Derivative
摘要:
An efficient synthesis of 1,8-naphthyridine-4(1H)-one sulfonamide derivatives by thermolysis of 2-pyridylaminomethylene (Meldrum's acid derivative) starting from 4,6-dimethyl-2-aminopyridine (1) is described.
