Herein, palladium-catalyzed Miyaura borylation of 4-bromo-2,4′-bithiazoles followed by Suzuki–Miyaura cross-coupling reaction (named the MBSC process) with (hetero)aryl- and alkenyl halides is reported. This methodology offers rapid access to various 2′,4-disubstituted 2,4′-bithiazole features including naturally-occurring 4-alkenylated and 4-pyridinylated 2,4′-bithiazoles. To prove its application, a concise approach for the synthesis of a heterocyclic cluster of the thiopeptide D-series antibiotic GE2270 is reported through a late-stage MBSC strategy.

Organic & Biomolecular Chemistry

Organic & Biomolecular Chemistry (OBC) publishes original and high impact research and reviews in organic chemistry. We welcome research that shows new or significantly improved protocols or methodologies in total synthesis, synthetic methodology or physical and theoretical organic chemistry as well as research that shows a significant advance in the organic chemistry or molecular design aspects of chemical biology, catalysis, supramolecular and macromolecular chemistry, theoretical chemistry, mechanism-oriented physical organic chemistry, medicinal chemistry or natural products. Articles published in the journal should report new work which makes a highly-significant impact in the field. Routine and incremental work is generally not suitable for publication in the journal. More details about key areas of our scope are below. In all cases authors should include in their article clear rationale for why their research has been carried out.
