Convenient synthesis of chromones and quinolinones

A one pot synthesis of substituted chromones and quinolinones by condensing commercially available and cheaper molecules like salicylic acid and anthranilic acid respectively with alkenes / nitriles followed by insitu cyclization using ammonium acetate as base has been achieved.

NEW REARRANGEMENT OF 2-ARYLMETHYLENE-3-INDOLINONES TO 2-AMINO-3-ARYL-4-QUINOLONES AND 2-(α-AMINOARYLMETHYLENE)-3-INDOLINONES

2-Arylidene-3-indolinones are converted by the action of sodium azide in a mixture of sulfuric and acetic acids into an easily separated mixture of 2-amino-3-aryl-4-quinolones and 2-(α-aminoarylmethylene)-3-indolinones.
