Organosoluble zirconium phosphonate nanocomposites and their supported chiral ruthenium catalysts: The first example of homogenization of inorganic-supported catalyst in asymmetric hydrogenation
In this article, we report the synthesis, structure, morphologies, and asymmetric catalytic properties of a series of novel organosoluble zirconium phosphonate nanocomposites and their supported chiral ruthenium catalysts, which have a good organosolubility (0.1–0.5 g mL−1) in various solvents and mesoporous, filiform, and layered structures. Due to the organosoluble properties in various organic solvents
在本文中,我们报告了一系列新型有机可溶物的合成,结构,形态和不对称催化性能 磷酸锆纳米复合材料及其负载的手性钌催化剂,在各种溶剂和介孔,丝状和层状结构中均具有良好的有机溶解度(0.1–0.5 g mL -1)。由于在各种有机溶剂中的有机可溶特性,在催化领域实现了膦酸锆负载的催化剂的第一次均质化。在取代的α-酮酯的不对称氢化中,对映选择性(74.3–84.7%ee)和分离的产率(86.7–93.6%)高于相应的均相Ru(p -cymene)(S -BINAP)Cl 2由于膦酸锆骨架中剩余的中孔引起的限制作用。反应完成后,通过添加可轻松以定量收率回收负载型催化剂环己烷 离心后再重复使用五次,而催化活性没有明显损失。

Stereoselective Titanium-Mediated Aldol Reactions of a Chiral Lactate-Derived Ethyl Ketone with Ketones
Aldol reactions of titanium enolates of lactate-derived ethylketone 1 with other ketones proceed in a very efficient and stereocontrolled manner provided that a further equivalent of TiCl4 is added to the reacting mixture. The scope of these reactions encompasses simple ketones such as acetone or cyclohexanone as well as other ketones that contain potential chelating groups such as pyruvate esters
