Amino-(N-alkyl) benzsulfamide synthesis method

The invention discloses an amino-(N-alkyl) benzsulfamide synthesis method. The method comprises the steps of adding aminobenzenesul fonamide, an iridium complex catalyst, alkali, compound alcohol and the solvent tert-amyl alcohol into a reaction container for reaction lasting several hours at 120-150 DEG C, then reducing temperature to room temperature, conducting rotary evaporation to remove the solvent, and then conducting column separation to obtain the target compound. Commercial aminobenzenesul fonamide and nearly non-toxic compound alcohol are used as starting materials, only water is generated as reaction byproduct, and no environment harm is done; reaction atom economy is high.

Effective Recognition of Different Types of Amino Groups: From Aminobenzenesulfonamides to Amino-(N-alkyl)benzenesulfonamides via Iridium-Catalyzed N-Alkylation with Alcohols

(Chemical Equation Presented). A simple, highly efficient, and general strategy for the direct synthesis of amino-(N-alkyl)benzenesulfonamides has been accomplished via direct N-alkylation of aminobenzenesulfonamides bearing both different types of amino groups with alcohols as alkylating agents. Notably, this research exhibited the potential for the recognition of different types of amino groups in the N-alkylation of complex molecules with alcohols, facilitating the progress of the transition-metal-catalyzed "hydrogen autotransfer (or hydrogen-borrowing) process."

Designer dendrimers: Branched oligosulfonimides with controllable molecular architectures

The synthesis of "designer" dendrimers and dendrons with sulfonimide units at every branching point is reported. The synthesis is based on a series of (regio)selective functionalization reactions of amines and sulfonamides allowing precise control of the
