We report the high-yielding, large-scale, one-pot synthesis of two versatile building blocks (1-Cl and 1-Br) for the regioselective synthesis of a variety of 2,3,5-trisubstituted pyridines from inexpensive materials. These molecules are readily derivatized at positions 2, 3, and 5. These building blocks can also be used for the synthesis of fused pyrido-oxazines and for the synthesis of 2,3,4,5-tetrasubstituted
我们报道了两种多功能结构单元( 1-Cl和1 - Br )的高产、大规模、一锅法合成,用于从廉价材料中区域选择性合成各种 2,3,5-三取代吡啶。这些分子很容易在位置 2、3 和 5 处衍生化。这些结构单元还可用于合成稠合吡啶并恶嗪和合成 2,3,4,5-四取代吡啶。
