(Chemical Equation Presented) A mild catalytic system to access diversely functionalized benzylic sulfonamides has been developed. Palladium-catalyzed α-arylation by Negishi cross-coupling of sulfonamide-stabilized anions and a wide range of aryl iodides, bromides, and triflates constitutes a practical strategy for the synthesis of various benzylic sulfonamides.

A novel series of 14 N-nitromethylsulfonanilide derivatives were synthesized and evaluated for their ability to inhibit recombinant aldose reductase. Computational docking simulations provided a good explanation for the observed structure-activity relatio

1H-Benzotriazol-1-yl methanesulfonate has been found to be an effective reagent in selective mesylation for differentiating amine groups from one another. In a molecule with both primary and secondary amine groups, mesylation only occurred at the primary amine group. When a compound contains both amine and hydroxy groups, the reagent selectively mesylated at the amine groups.
Aminolysis of sulfinamoyl-esters, -sulfonamides and -sulfones. Thiooxamate and thiourea formation via a sulfine intermediate. Thiophilic or carbophilic reaction?

, p. 14865 - 14876 (2007/10/03)
The aminolysis process of sulfinamoyl derivatives was investigated with sulfinamoyl esters. An intermediate sulfine was unambiguously evidenced by formation of a Diels-Alder type adduct. The aminolysis leads to final thiooxamate products. A carbophilic addition was suggested for the reaction with secondary amines. With sulfinamoyl, -sulfones and -sulfonamides, a thiourea is formed resulting from a double aminolysis.
SUBSTITUENT EFFECT TREATMENT OF INTERACTIONS BETWEEN CONTIGUOUS FUNCTIONALITIES. IV. RESTRAINT TO PHENYL-NITROGEN CONJUGATIVE INTERACTION IN N-FUNCTIONALIZED N-METHYLANILINES

13C shifts at the para position in PhN(Me)X for 17 different substituents X serve as monitors for investigating, in correlative analysis, the nature and the extent of interactions occurring between the substituent X and the N-Me cavity.For the majority of substituent, X, partitioning of the nitrogen electron pair between the phenyl and the substituent is partially hampered because of the non-zero twist angle between the planes containing the phenyl ring and the Me-N-X fragment.As a consequence, relative to PhNHX, the interactions between the cavity and the substituents are increased in intensity, especially their mesomeric component, and, at the same time, para-13C shifts are displaced toward lower field.Evidence is also provided that possible H-bonding by the NH cavity of PhNHX with dimethyl sulphoxide does not appreciably influence the substituent electron demand determined previously.
