Article abstract of DOI:10.1016/0040-4039(94)88327-0

The irradiation of tertiary amines in the presence of ketones leads to a regioselective and stereoselective formation of iminium salts which then react to afford the corresponding oxazines or oxazoles. - Key words : Ammoniumyl ions, iminium ions, electron transfer, amines, ketones, tetrahydro<1,3>oxazine tetrahydrooxazoles.
