通过简单浸渍负载在周期性介孔甲阶酚醛树脂上的铂纳米颗粒在用辛可尼定手性修饰后可作为有效、稳健且可重复使用的催化剂，用于丙酮酸乙酯的不对称氢化，提供高达 62% 的对映体过量 (ee) 和在 25 次重复使用后保持恒定的活性。他们还可以通过使用水作为溶剂以环境友好的方式催化反应。
Platinum nanoparticles supported on periodic mesoporous resols by simple impregnation serve as effective, robust and remarkably reusable catalysts after chirally modified with cinchonidine for the asymmetric hydrogenation of ethyl pyruvate, affording up to 62% enantiomeric excess (ee) and a constant activity after 25th re-use. They can also catalyze the reaction in an environmentally benign manner by using water as a solvent.
