Carbodiimide insertion into sulfonimides: one-step route to azepine derivatives via a two-atom saccharin ring expansion
Tan, Davin,Fri??i?, Tomislav
, p. 901 - 904 (2017)
A previously unknown insertion of carbodiimides into sulfonimides enables the first one-step, two-atom expansion of the saccharin 5-membered ring into a 7-membered benzo[1,2,4]thiadiazepine, and a two-atom chain extension of a non-cyclic sulfonimide. This reaction is enhanced by copper salts, which allow it to be conducted mechanochemically, in a solvent-free manner.

Some new sulfonylurea derivatives (2a-j) of saccharin have been obtained by the reaction of ethyl 3-oxo-1,2-benzisothiazole-2(3H)-carboxylate 1,1-dioxide (1) with the appropriate amine. Ethyl 3-oxo-1,2-benzisothiazole-2(3H)-carboxylate 1,1-dioxide was obt
