Abstract:

Pyridoxal undergoes oxa-Michael initiated ring closure with 2-(trifluoromethyl)chromones giving 11a,13-dihydro-6H-1-benzopyrano{[}3',2':6,7]oxepino{[}3,4-c]pyridin-6-on es and 6H,11aH-1-benzopyrano{[}3',2':5,6]pyrano{[}2,3-c]pyridin-6-ones. Participation of alcoholic hydroxy group of pyridoxal in the initial oxa-Michael addition leads to the former product and that of the phenyl hydroxy group to the later one. (C) 2012 Elsevier B.V.
