Controllable assembly of the benzothiazole framework using a CC triple bond as a one-carbon synthon?
Chemical Communications Pub Date: 2018-01-23 DOI: 10.1039/C7CC09855C
Abstract
A concise and efficient protocol to assemble diverse benzothiazole derivatives in high yields was provided via copper catalyzed tandem cyclization with o-haloanilines, elemental sulfur and terminal alkynes as raw materials. In this protocol, C atoms on the C![[triple bond, length as m-dash]](https://www.rsc.org/images/entities/char_e002.gif)
C triple bond were controllably involved in the construction of the benzothiazole framework and multiple carbon–heteroatom bonds through divergent routes.
