## Abstract The hetero DielsโAlder reaction of the enamino ketones 1b and 1c with ethyl vinyl ether (2) in dichloromethane to give the dihydropyrans 3b/4b and 3c/4c is studied at high pressure up to 5 kbar. The kinetics is measured by onโline FTโIR spectroscopy up to 3 kbar. The cycloadditions show
