The synthesis of a novel supramolecular tetrahedral assembly of K12Ga4L6 stoichiometry is reported. The newly designed chiral ligand exhibits high diastereoselective control during cluster formation, leading exclusively to a single diastereomer of the desired host. This new assembly also exhibits high stability toward oxidation or a low pH environment and is a more robust and efficient catalyst for asymmetric organic transformations of neutral substrates.
本文报道了一种新型超分子四面体 K12Ga4L6 配合物的合成。新设计的手性配体在形成簇时表现出高的非对映选择性控制,仅得到所需主体的单一非对映异构体。这种新的组装体对氧化或低 pH 环境也表现出高的稳定性,并且是更有效的不对称有机转化的中性底物的催化剂。
