with hydroxymethyl groups at positions 3 and 4 of the pyridine ring have been implemented based on the transformations of 2-halopyridine-3,4-dicarbonitriles. The first path involves obtaining target compounds with a halogen atom in the 2-position of pyridine by reduction of intermediate pyridine-3,4-dicarboxylates with sodium borohydride. The second approach is based on the reduction of annelated furo[3
摘要 基于 2-卤代吡啶-3,4-二甲腈的转化,已经实施了两种合成吡啶环 3 位和 4 位具有羟甲基的官能化吡哆醇衍生物的新方法。第一条途径涉及通过用硼氢化钠还原中间体吡啶-3,4-二羧酸盐来获得在吡啶的2-位具有卤素原子的目标化合物。第二种方法基于还原呋喃[3,4- c ]吡啶-3(1 H )-酮,并允许获得2-卤素-和2-烷基氨基-取代的吡哆醇衍生物。
