## Abstract Synthesis of 1,2‐disubstituted‐3‐hydroxy‐4(1__H__)‐quinolinones by the cyclization of __N__‐substituted phenacyl or acetonyl anthranilates is described. Two methods were employed for cyclization of anthranilates. Heating in polyphosphoric acid has a wide scope of applicability. The ther
