| Abstract: | Dihydro-(2H)-1 .2.4-benzothiadizine-1. 1-dioixdes were prepared in good yields via reductive cyclization of o-nitrobenzenesulfonamidcs with aldchydes promoted by Sml2 under mild and neutral condition. |
| Keywords: | Samarium diiodide 2H-1 2 4-benzothiadizinc-1. 1 -dioxide. reductive cyclization. |
