Abstract

A modular access to 2,4 disubstituted benzothiazoles has been achieved though the intermediacy of 4-bromo-2-iodobenzothiazole. The difference in reactivity of both halogens was advantageously exploited to achieve sequential Suzuki-Miyaura cross-coupling giving access to a range of polyaromatic derivatives featuring a central benzothiazole core.

Keywords: Orthogonal Suzuki-Miyaura cross coupling; benzothiazole; boronic derivatives.
