Abstract
The Diels–Alder reactions of ethyl 3-benzamido-2-oxo-6-(trifluoromethyl)-2H-pyran-5-carboxylate with ethyl vinyl ether, 2-methoxypropene, and 1-ethoxypropene were investigated. Under different reaction conditions, intermediate oxabicyclo[2.2.2]octenones, alkoxycyclohexadienes, or aromatic products [5-benzamido-2-(trifluoromethyl)benzoates] were formed. The reaction is useful for the preparation of some hitherto unknown trifluoromethyl-containing derivatives of 3-aminobenzoic acid.
