series of chiral bicyclic guanidines, either symmetrical or non-symmetrical, was synthesized using a concise and efficient aziridine-based synthetic methodology. Starting from commercial amino alcohols, five synthetic steps were performed, with only three requiring chromatographic purification, giving the desired guanidines in 43–71% overall yield. Preliminary studies using these guanidines showed moderate
使用简洁有效的基于氮丙啶的合成方法合成了一系列对称或不对称的手性双环胍。从商业氨基醇开始,进行了五个合成步骤,仅三个步骤需要进行色谱纯化,以43-71%的总收率得到所需的胍。使用这些胍的初步研究表明,对几种迈克尔反应具有中等对映选择性。
