product. Various new cis- and trans-1-(teri-butylamino)-2-benzyl- 2-methylcyclopropane-carbonitriles and the corresponding cyclopropanecarboxamides have been synthesized, with focus on the isolation of the pure stereoisomeric cyclopropanecarboxamides. The relative configuration of the stereoisomers was established by X-ray crystallographic analysis of one of the model compounds. A new route to the latter
2-氨基-4-氯-3,3-二甲基丁腈与叔丁醇钾在THF中的直接环化得到1-氨基-2,2-二甲基环丙烷-1-腈和二聚产物。已经合成了各种新的顺式和反式 1-(叔丁基氨基)-2-苄基-2-甲基环丙烷甲腈和相应的环丙烷甲酰胺,重点是纯立体异构环丙甲酰胺的分离。立体异构体的相对构型是通过一种模型化合物的 X 射线晶体学分析建立的。通过 1-甲氧基环丙胺与氰化钾的反应,开发了获得后者官能化环丙烷的新途径。报道了通过 Favorskii 衍生的中间体将 1-氨基环丙烷-1-腈重排为氮杂环丁烷和恶嗪衍生物的一些显着重排。
