One-Pot synthesis of sulfonamides from primary and secondary amine derived sulfonate salts using cyanuric chloride

A convenient, mild and efficient one-pot synthesis of new sulfonamides is described. The reaction of primary or secondary amine derived sulfonate salts in the presence of cyanuric chloride, triethylamine as base, and anhydrous acetonitrile as solvent at room temperature gives the corresponding sulfonamides in good to excellent yields.

THE REACTION OF ETHYL-FORMIMIDATE WITH GRIGNARD REAGENTS: A NEW APPROACH TO ELECTROPHILIC AMINATION

Addition of Grignard reagents to ethyl-N-(diethoxyphosphoryl)formimidate, 3 followed by aqueous workup and treatment of the resultant diethyl phosphoramidates with p-toluenesulfonic acid in ethanol gives, depending upon the organomagnesium reagent used, the corresponding tosylates of primary or secondary amines in moderate to good yields.The diethoxyphosphoryl moiety remains unchanged upon treatment of 3 with Grignard reagents.Key words: Diethyl-(N-alkylphosphoramidates); Grignard reagents; ammonium tosylates; substitution-addition; substitution-reduction; electrophilic amination.
