Herein, we report Cp Ir(III)-catalyzed C-H/O-H-bond functionalization of salicylaldehydes with α-diazocarbonyl compounds for the synthesis of chromones under redox-neutral conditions. The reaction proceeds at room temperature and displays excellent functi
Synthesis of Benzopyranoisoxazol-4-ones from 2-Substituted Chromone-3-carboxylic Esters. A Reinvestigation of the Reaction of 3-Acetyl-4-hydroxycoumarins with Hydroxylamine. Synthesis of 4-(2-Hydroxybenzoyl)isoxazol-5-ones

A convenient method for the synthesis of ethyl 2-substituted chromone-3-carboxylates by the condensation of o-acetoxyaroyl chlorides with β-keto esters is described.These chromones are converted into the corresponding 4H-benzopyranoisoxazol-4-on
