Abstract

Reaction of sodium azide with chromone-2-carbonyl chloride or the action of nitrous acid on the hydrazide of chromone-2-carboxylic acid, existing in the cyclic form 3′-oxopyrazolidino[4′,5′∶2, 3]-chroman-4-one, gives the azide of chromone-2-carboxylic acid, the Curtius rearrangement of which is used to synthesize a number of 2-acylaminochromones.
