The synthesis of two new α-aminophosphonic acids, namely (2S*,3aS*,7aS*)- and (2R*,3aS*,7aS*)-octahydroindole-2-phosphonic acids, is described. They are analogues of phosphoproline with a cyclohexane ring fused to the pyrrolidine moiety. The ring junction has cis stereochemistry in both cases, but the two compounds differ in the relative orientation of the cyclohexane and phosphonate moieties. The
描述了两种新的 α-氨基膦酸,即 (2S*,3aS*,7aS*)-和 (2R*,3aS*,7aS*)-octahydroindole-2-膦酸的合成。它们是具有与吡咯烷部分稠合的环己烷环的磷酸脯氨酸类似物。在这两种情况下,环接点都具有顺式立体化学,但是这两种化合物的环己烷和膦酸酯部分的相对取向不同。这两种氨基酸是按照提供具有完全立体控制的所需立体异构体的立体发散路线从共同起始材料制备的。合成的化合物的相对构型通过X射线衍射分析证实。
