Reaction of propane-1, 3-sultone with amines gave N-substituted aminosulphonnic acids 2a-i, Dehydration of 2a-c with $POCI_3$ gave the corresponding sultams 3a-c. Propane-1, 3-sultone 1 reacted with tertury amines to give the betaiene salts 4-11. 2-4-Dimethyl-1, 3-butadiene-1, 4-sultone 12 condensed with amines to give N-substituted-2, 4-dimethyl-1, 3-butadiene-1, 4-sultames 13a and 13b. The reaction of 3a, 13a with hydrazine hydrate gave acid hydrazides 3d or 13c. Compounds 3d, 13c reacted with isocyanates to yield urea derivatives 14a-c, 15a-c.
