摘要

Summary: Conjugated nitrosoalkenes, generated in situ via dehydrobromination of a- bromoketoximes, undergo an easy [4+ 21-cycloaddition with thiocarbonyl compounds to give very high yields of the new heterocycles 4H-1, 5, 2-oxathiazines. The thermolysis and the behaviour to oxidation of these adducts were tested.
