Catalytic asymmetric synthesis of carbocyclic C-nucleosides

S. Mishra, F. C. T. Modicom, et al.

Discover a groundbreaking method for synthesizing carbocyclic C-nucleosides that overcomes lengthy processes and poor modularity. Researchers Sourabh Mishra, Florian C. T. Modicom, Conor L. Dean, and Stephen P. Fletcher introduce an innovative asymmetric Suzuki-Miyaura reaction, enabling the formation of diverse enantiomerically enriched CC-Ns, including a unique carbocyclic derivative of Showdomycin.

Abstract
Access to carbocyclic C-nucleosides (CC-Ns) is currently restricted. The few methods available to make CC-Ns suffer from long syntheses and poor modularity, hindering the examination of potentially important chemical space. Here we report an approach to CC-Ns which uses an asymmetric Suzuki-Miyaura type reaction as the key C-C bond forming step. After coupling the densely functionalized racemic bicyclic allyl chloride and heterocyclic boronic acids, the trisubstituted cyclopentenyl core is elaborated to RNA analogues via a hydroborylation-homologation-oxidation sequence. We demonstrate that the approach can be used to produce a variety of enantiomerically enriched CC-Ns, including a carbocyclic derivative of Showdomycin.
