S 8-Mediated Cyclization of Bis(2-aminophenyl) Disulfide/Diselenide with Arylacetylenes/Styrenes: Access to 2-(Arylmethyl)-1,3-benzothiazoles/benzoselenazoles

A novel S8-mediated approach to benzothiazoles/benzoselenazoles from bis(2-aminophenyl) disulfides/diselenides and phenylacetylenes or styrenes has been developed. 2-(Arylmethyl)-1,3-benzoselenazoles were comprehensively synthesized for the first time. The reactions proceeded in moderate to excellent yields, and with a gramscale application.

Photocatalytic synthesis method of C2 substituted 2H-benzothiazole benzylated derivative

The invention discloses a photocatalytic synthesis method of a C2 substituted 2H-benzothiazole benzylated derivative. The photocatalytic synthesis method comprises the following steps of: mixing 2H-benzothiazole with substituted methyl benzene; adding an oxidizing agent Selectfluor, an additive trifluoroacetic acid and a solvent acetonitrile, carrying out a normal temperature stirring reaction under the protection of nitrogen and the irradiation of an LED blue light lamp, carrying out TLC monitoring until the reaction is finished, and carrying out separation and purification on the reaction liquid to obtain the C2 substituted 2H-benzothiazole benzylated derivative. The new method for synthesizing the C2 substituted 2H-benzothiazole benzylated derivative through visible light induction by taking Selectfluor as an oxidizing agent, trifluoroacetic acid as an additive and acetonitrile as a solvent is high in atom economy, simple in catalytic system, good in product yield, wide in substraterange and suitable for popularization and application.

Selective Construction of 2-Substituted Benzothiazoles from o-Iodoaniline Derivatives S8 and N-Tosylhydrazones

Selective construction of 2-substituted benzothiazoles from o-iodoaniline derivatives S8 and N-tosylhydrazone via a copper-promoted [3 + 1 + 1]-type cyclization reaction has been realized. In the protocol, the carbon atom on N-tosylhydrazone could be regulated to construct benzothiazole by changing the reaction system. Furthermore, the transformation has achieved the construction of multiple carbon-heteroatom bonds.
