C-H alkenylation/cyclization and sulfamidation of 2-phenylisatogens using: N -oxide as a directing group

The first example of transition-metal-catalyzed C-H activations of 2-phenylisatogens with alkynes and sulfonyl azides has been developed using N-oxide as the directing group. Ru(ii)-Catalyzed C-H alkenylation/cyclization and Ir(iii)-catalyzed direct C-H sulfamidation proceeded with good yields and excellent functional group tolerance. Importantly, these two transformations provided straightforward routes for the synthesis of indol-3-one derivatives and sulfamidated 2-phenylisatogens respectively, which might be of considerable bioactivities.

Enamines: Part V - Synthesis of Substituted Phenyl Benzyl Ketones and 2-Arylisatogens

Three different approaches of o/p-nitrophenyl benzyl ketones and their limitation in the synthesis of 2-arylisatogens are described.

Antitubercular Agents : Part III - Synthesis of Substituted 2-Arylisatogens

A number of 2-arylisatogens (VII) have been prepared starting from o-nitroacetophenones (I).Condensation of I with different aromatic aldehydes (II) gives the corresponding o-nitrochalkones (III) which on epoxidation followed by treatment with BF3-etherat
