In the title compound, C(7)H(7)N(5)O(2)S, the aromatic ring is oriented at dihedral angles of 79.46 (2) and 89.17 (2)°, respectively, with respect to the amino-(azido)-methyl and the S(6) six-membered ring motif generated by an intra-molecular N-H⋯O inter-action [N⋯O = 2.8901 (15) Å]. Inter-molecular N-H⋯O hydrogen bonds [N⋯O = 2.9177 (15) and 2.9757 (15) Å] generate an infinite one-dimensional...

In the title compound, C(23)H(20)N(2)O(3)S(2), the phenylsulfonyl ring and phenylthio ring make dihedral angles of 66.5 (7) and 81.2 (6)°, respectively, with the indole unit. In the crystal, mol-ecules are linked into centrosymmetric dimers via pairs of N-H⋯O hydrogen bonds with graph-set motif R(2) (2)(14). The crystal structure is further stabilized by weak inter-molecular C-H⋯O and very weak...

A difluorinated dienophile underwent cycloaddition reactions with a range of furans to afford cycloadducts which could be processed regio- and stereoselectively via episulfonium ions, generated by the reaction between their alkenyl groups and phenylsulfenyl chloride. The oxabicyclic products were oxidised to the phenylsulfonyl level and ring opened via E1(C)B or reductive desulfonative pathways...

A highly efficient organocatalytic sequential reaction involving Michael addition of bis(phenylsulfonyl)ethylene, in situ condensation and intramolecular nitrone [3+2] cycloaddition with a variety of aldehydes and hydroxyamines to afford a single diastereomer of indanes with four stereogenic centers in excellent yields and stereoselectivities was developed.

ABSTRACT A series of novel phenylsulfonyl- and 4-aminophenylsulfonyl-carboximidamides were synthesized by condensation of sulfonamides with heterocyclic methyl carbimidates obtained from heterocyclic carbonitriles and used 'at its inception.' The molecular structure of the obtained compounds is discussed. Compounds possessing heterocyclic systems with a nitrogen atom in the α position to the fu...

The choice is yours: a highly stereoselective synthesis of α-alkyl-α-hydroxy-β-amino esters is accomplished through a tandem Wittig-rearrangement/Mannich reaction sequence. Transformations of N-benzyl or N-Boc imines proceed with high selectivity for formation of syn-amino alcohol derivatives, whereas N-Boc-2-(phenylsulfonyl)amines generate anti-amino alcohol products. Auxiliary cleavage (trans...
