KI-catalyzed arylation of benzothiazoles from the coupling of aryl aldehydes with benzothiazoles in neat water.
A KI-catalyzed oxidative coupling of benzothiazoles with aryl aldehydes has been developed using TBHP as an oxidant in neat water under metal free conditions. Various 2-aryl benzothiazoles were prepared in 36-79% yields for 28 examples. The mechanistic studies suggested that this transformation proceeded via a radical process.

متن کاملDirect arylation of benzothiazoles and benzoxazoles with aryl boronic acids.
Aryl-substituted benzothiazoles and benzoxazoles are an important class of heterocyclic compound and have shown a wide range of biological activities, such as antitumor, antiviral, and antimicrobial activities. In addition, these compounds have become essential building blocks for the synthesis of conjugated functional materials, such as industrial dyes and plant growth regulators. The conventi...
متن کاملDesign and synthesis of 2-acylbenzothiazoles via in situ cross-trapping strategy from benzothiazoles with aryl ketones.
An I2/KOH synergistically promoted direct ring-opening aroylation of benzothiazoles with aryl ketones has been discovered. Aryl ketones were seen to act as carbonyl sources to construct 2-acylbenzothiazoles. This reaction could provide an example for the convergent integration of self-labor domino sequences based on an in situ cross-trapping strategy.
