A scalable de novo synthesis of difluoromethyl pyridines from inexpensive materials is reported. The pyridyl subunit is built around the difluoromethyl group rather than a late stage introduction of this moiety. This user-friendly approach allows access to a diverse range of substitution patterns on all positions on the ring system and on the difluoromethyl group.

The difluoromethyl group is a crucial fluorinated moiety with distinctive biological properties, and the synthesis of chiral CF₂H-containing analogs has been recognized as a powerful strategy in drug design. To date, the most established method for accessing enantioenriched difluoromethyl compounds involves the enantioselective functionalization of nucleophilic and electrophilic CF₂H synthons. However, this approach is limited by lower reactivity and reduced enantioselectivity.

The incorporation of aromatic difluoromethyl motifs has proven to be a fruitful strategy for enhancing the therapeutic profiles of modern pharmaceutical candidates. While the defluorofunctionalization of trifluoromethylarenes offers a promising pathway toward diverse aromatic difluoromethyl compounds, current methods are predominantly limited to two-component reactions. Multicomponent cascade reactions (MCRs) involving a transient aromatic difluoromethyl radical are still uncommon and highly sought after, owing to their capacity to rapidly generate challenging molecular structures.
