چکیده
In the title compound, C(10)H(11)NO(3)S, the benzisothia-zole ring system is almost planar [maximum deviation = 0.030 (1) Å for the S atom]. The isoprop-oxy group is almost in the plane of the benzisothia-zole ring system [N-C-O-C = 4.5 (2)°] with one of its methyl groups in an anti-periplanar orientation relative to the benzisothia-zole ring system [C-C-O-C = -162.0 (2)°].

The title mol-ecule, C(10)H(9)NO(5)S, is composed of two essentially planar units with a dihedral angle of 89.16 (6)° between them. In the crystal structure, there are weak inter-molecular C-H⋯O inter-actions resulting in dimeric pairs of mol-ecules about inversion centres and chains of mol-ecules extended along the a and c axes, thus stabilizing the structure. In addition, benzothia-zole rings...

The title compound, C32H32O6, crystallized with two independent molecules in the asymmetric unit. Each molecule has essentially the same feature of non-coplanar aromatic rings whereby the two 4-isopropoxybenzoyl groups are twisted in a perpendicular manner to the naphthalene ring and oriented in the same direction (syn-orientation). The benzene rings of the aroyl groups make dihedral angles of ...
متن کاملGeneration of 4-((trifluoromethyl)thio)-2H-benzo[e][1,2]thiazine 1,1-dioxides via a reaction of trifluoromethanesulfanylamide with 2-(2-alkynyl)benzenesulfonamide.
The incorporation of the (trifluoromethyl)thio group into the benzo[e][1,2]thiazine 1,1-dioxide scaffold via a reaction of trifluoromethanesulfanylamide with 2-(2-alkynyl)benzenesulfonamide is reported. The transformation proceeds under mild conditions to afford the 4-((trifluoromethyl)thio)-2H-benzo[e][1,2]thiazine 1,1-dioxides in moderate to good yields.
