CYCLOADDITION REACTIONS OF N-SULPHINYLCARBOXAMIDES. I. REACTIONS WITH SYMMETRICALLY SUBSTITUTED ALKENES

The reaction of N-sulphinyl-p-toluamide and -acetamide with some representative symmetrically substituted alkenes yielded 5,6-disubstituted-5,6-dihydro-1-oxa-4-thia-3-azine 4-oxides, 2.Structures were assigned on the basis of chemical behaviour and IR and 1H-NMR spectra of the same adducts and of the corresponding oxidation products; in particular, it could be ascertained that the alkenes retained their configuration in the cycloaddition reaction.Hydrolysis of some of the oxidation products gave ring opening and allowed to obtain the corresponding esters of 2-hydroxy-alkanesulphonamides.
