6-oxa-3-azabicyclo[3.1.1]heptane (2a) is of particular interest as a morpholine isostere because it is achiral and shows properties similar to that of morpholine based on a derived analogue. The first synthesis of morpholine 2a (tosylate salt) is described. The six-step sequence begins with inexpensive starting materials and uses straightforward chemistry. stereoselective synthesis - bicyclic compounds
桥接的双环吗啉是药物化学研究的重要组成部分。双环吗啉6-氧杂-3-氮杂双环[3.1.1]庚烷(2a)作为吗啉等排物特别受关注,因为它是非手性的,并且显示出与基于衍生类似物的吗啉类似的性质。描述了吗啉2a(甲苯磺酸盐)的首次合成。六步序列从廉价的起始原料开始,并使用简单的化学方法。 立体选择性合成-双环化合物-杂环-烷基化-加氢
