Alkanol derivatives corresponding to the general formula I R.sup.1 R.sup.2 N--(CH.sub.2).sub.m --Q--CH.sub.2 X--CH.sub.2 --Y--(CH.sub.2).sub.n --NHR.sup.3 (I) which have a highly selective action on histamine-H.sub.2 receptors are described. Due to this action, these compounds may advantageously be used for treatment of diseases caused by raised gastric secretion.

Substituted epoxy alcohols and amines allow substrate‐controlled conversion of CO2 into a wide range of heterocyclic structures through different mechanistic manifolds. This new approach results in an unusual scope of CO2‐derived products by initial activation of CO2 through either the amine or alcohol unit, thus providing nucleophiles for intramolecular epoxy ring opening under mild reaction conditions
取代的环氧醇和胺可通过不同的机械歧管,将底物控制的CO 2转化为多种杂环结构。这种新方法通过胺或醇单元对CO 2的初始活化,导致了源自CO 2衍生产品的异常范围,从而在温和的反应条件下为分子内环氧开环提供了亲核试剂。对照实验通过遵循S N i途径的亲核试剂开环步骤和5-exo-tet环化作用,支持了胺/醇片段在该过程中的关键作用,从而形成了杂环骨架。
