(IDP) into two Dy metal-organic frameworks (MOFs) allows controlling the organocatalyst conformations and local chiral microenvironments. The MOF containing the 4-connected IDPs has a less compact shape and can be an efficient and recyclable heterogeneous Brønsted acid catalyst for the challenging asymmetric O,O-acetalization of diol and aldehyde with up to 96 % ee.
将手性 1,1'-双酚基亚氨基二磷酸 (IDP) 网状化为两个 Dy 金属有机框架 (MOF) 可以控制有机催化剂构象和局部手性微环境。包含 4-connected IDPs 的 MOF 具有不太紧凑的形状,可以作为一种高效且可回收的非均相 Brønsted 酸催化剂,用于具有挑战性的二醇和醛的不对称 O, O-缩醛化,ee 高达 96%。
