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氟甲基吡啶。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。
