catalytic cascade reaction of α‐ketoacids and aldehydes is achieved using the title catalyst and water as the solvent. Fluorescence imaging shows that the catalyst is mainly distributed on the surface of emulsion droplets. Optically active isotetronic acids can be obtained with this method and the emulsion droplets are responsible for the high reactivity and enantioselectivity.
放下!使用标题催化剂和水作为溶剂,可以实现α-酮酸和醛类的高度对映选择性催化级联反应。荧光成像表明,催化剂主要分布在乳液液滴的表面。可以用这种方法获得旋光性的等渗酸,并且乳液液滴是导致高反应性和对映选择性的原因。
