Canonical nucleosides are vulnerable to enzymatic and chemical degradation, yet their stable mimics—C-aryl nucleosides—have demonstrated potential utility in medicinal chemistry, chemical biology, and synthetic biology, although current synthetic methods remain limited in terms of scope and selectivity. Herein, we report a cross-electrophile coupling to prepare C-aryl nucleoside analogues from readily available furanosyl acetates and aryl iodides. This nickel-catalyzed modular approach is characterized by mild reaction conditions, broad substrate scope, excellent β-selectivity, and high functional-group compatibility. The exclusive chemoselectivity with respect to the aryl iodide enables efficient preparation of a variety of C-aryl halide furanosides suitable for various downstream transformations. The practicality of this transformation is demonstrated through the synthesis of a potent analogue of a naturally occurring NF-κB activator.

The glycosylation of various aglycones with 5-O-benzoyl-2,3-O-isopropylidene-β-D-ribofuranosyl bromide (2) has been studied under different reaction conditions.It is possible to obtain high yields of α-linked ribofuranosides using methanol or methyl-2,3-O
