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.
据报道,由廉价的材料可规模化地从头合成二

吡啶基亚基围绕二
氟甲基基团构建,而不是该部分的后期引入。这种用户友好的方法允许在环系统和二
氟甲基上的所有位置上获得各种各样的取代模式。
