The development of catalytic, enantioselective halofunctionalizations of unactivated alkenes has made significant progress in recent years. However, the identification of generally applicable catalysts for wide range of substrates has yet to be realized. A detailed understanding of the reaction mechanism is essential to guide the formulation of a truly general catalyst. Herein, we present our investigations on the enantiodetermining step of a Lewis base catalyzed bromocycloetherification that provides important insights and design criteria.
最近几年来,对于未活化烯烃的催化、对映选择性卤代功能化反应取得了显著进展。然而,尚未实现对广泛底物适用的通用催化剂的识别。对反应机理的详细理解对于指导真正通用催化剂的制定至关重要。在这里,我们介绍了我们对路易斯碱催化溴环氧烷化反应中的对映决定步骤的研究,提供了重要的见解和设计准则。
