The stereocontrolled synthesis of a range of substituted bicyclic morpholine and piperazine derivatives is reported from substituted pyroglutaminols via an intramolecular SN2 cyclization as the key step. This enantiospecific approach toward chiral bicyclic morpholines and piperazines offers new opportunities to access these challenging ring systems, which are becoming increasingly common motifs in
据报道,通过分子内S N 2环化作用,由取代的焦谷氨醇经立体控制合成了一系列取代的双环吗啉和哌嗪衍生物,这是关键步骤。这种手性双环吗啉和哌嗪的对映体特异性方法为使用这些具有挑战性的环系统提供了新的机会,这些环系统在药物发现中正变得越来越普遍。
