synthetic route leading to 4-methoxypyridopyrimidines is described. The first lithiation and functionalization of the pyridine moiety has been studied. According to various structural parameters, the regioselectivity of the metallation is discussed. The functionalization of the 4-methoxypyridopyrimidines via the metallation reaction, provides an efficient process to access new substituted pyridopyrimidines
从吡啶并嘧啶-4(3 H)-1开始,描述了导致4-甲氧基吡啶并嘧啶的一般合成路线。已经研究了吡啶部分的第一次锂化和官能化。根据各种结构参数,讨论了金属化的区域选择性。通过金属化反应对4-甲氧基吡啶并嘧啶进行官能化,提供了一种有效的方法来获得新的取代的吡啶并嘧啶。
