The catalyst loading in the narrow range between 0.5 and 10 mol % determines whether an enantioselective organocatalytic aldol reaction proceeds under kinetic or thermodynamic control; high conversions and ee values can be achieved with low catalyst loadings (see scheme). Since the reaction is carried out in water, it can be combined with a biocatalytic reduction for the one‐pot synthesis of 1,3‐diols
在0.5和10mol%之间的窄范围内的催化剂载量决定了对映选择性的有机催化醛醇缩合反应是在动力学或热力学控制下进行的。催化剂用量低时,可以实现高转化率和ee值(请参见方案)。由于该反应是在
水中进行的,因此可以与
生物催化还原相结合,以一锅法合成dr> 25:1和ee为99%的1,3
-二醇 。
