Cyclobutane diamines (i.e., cis- and trans-1,3-diaminocyclobutane, 6-amino-3-azaspiro[3.3]heptane, and 3,6-diaminospiro[3.3]heptane) are considered as promising sterically constrained diamine building blocks for drug discovery. An approach to the syntheses of their Boc-monoprotected derivatives has been developed aimed at the preparation of multigram amounts of the compounds. These novel synthetic
环丁烷二胺(即顺式和反式-1,3-二氨基环丁烷,6-氨基-3-氮杂螺[3.3]庚烷和3,6-二氨基螺[3.3]庚烷)被认为是有前途的受空间约束的二胺结构药物发现。已经开发了合成其Boc单保护衍生物的方法,旨在制备多克量的化合物。这些新颖的合成方案利用经典的丙二酸酯烷基化化学方法来构建环丁烷环。环丁烷二胺衍生物的构象偏好已通过X射线衍射进行了评估,并与空间受限的二胺的文献数据进行了比较,后者是市售药物的组成部分。
