A New Strategy for the Synthesis of Pyridine Amides, Phosphorylated Quinoline Amides and Their Thio-Analogues

Nycz J. E.

1637-1642

A new strategy for the synthesis of pyridine amides, phosphorylated quinoline amides and their thio-analogues has been developed. The direct reaction between in situ generated mixed phosphoric-carboxylic anhydrides with primary amines al lowed a simultaneous phosphorylation (thiophosphorylation) and amidation of hydroxyquinoline acids. In the absence of hydroxyl group, quinoline and pyridine acids were smoothly converted into amides.
