Abstract
Dianions of alkanesulfonamides add to nitriles, and the resultant imine dianions are cyclized with a carbonyl equivalent to afford the known 2H-1,2,4-thiadiazin-3-(4H)-one 1,1-dioxide ring system. The use of aldehydes as electrophiles provides the novel 5,6-dihydro-1,4,3-oxathiazin-2(3H)-one 4,4-dioxide ring system.
