Synthesis of α-azido-2′-hydroxychalcones from chalcone dibromides with azide ion
Patonay, Tamas,Jekoe, Jozsef,Riman, Eva
, p. 2403 - 2415 (2002)
The reaction of the 2′-hydroxychalcone dibromides with azide ion was found to afford various products such as α-azido-2′-hydroxychalcones, flavones, aurones, isoxazoles or the parent chalcones depending on the substituent pattern of the substrate. Efficie
