Synthesis of enantiopure β2-homoalanine derivatives via rhodium catalyzed asymmetric hydrogenation
摘要:
The stereoselective synthesis of chiral beta(2)-homoalanine derivatives with 99% ee by the Rh-catalyzed enantioselective hydrogenation of prochiral 2-aminomethyl acrylates is described. The subsequent transformation to chiral 3-amino-2-methylpropanols is also demonstrated. (c) 2013 Elsevier Ltd. All rights reserved.

Chiral naphthalene diimide ligands (NDIPhos) were exploited in rhodium-catalyzed enantioselective hydrogenation. The key feature of these ligands is their ability to self-assemble via π–π interactions to mimic bidentate ligands, offering a complementary method to traditional supramolecular strategies. This concept was further substantiated by computations with the composite electronic-structure method
手性萘二酰亚胺配体 (NDIPhos) 被用于铑催化的对映选择性氢化。这些配体的关键特征是它们能够通过π-π 相互作用自组装以模拟双齿配体,为传统的超分子策略提供了一种补充方法。复合电子结构方法 r 2 SCAN-3c 的计算进一步证实了这一概念。
