A Scalable and Regioselective Synthesis of 2‑Difluoromethyl Pyridines from Commodity Chemicals
2014-03-21T00:00:00Z (GMT) by
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.
