L-2-Hydroxyaldehydes L-3 with a great variety of substituents in 3-position are obtained in good chemical and excellent optical yields by kinetic resolution in the transketolase-catalyzed reaction of racemic 2-hydroxyaldehydes with lithium hydroxypyruvate 4 where only the enantiomer (R)-3 reacts to 5-deoxy-D-xyluloses 5.
L-2-羟基醛L- 3在3位上有很大的各种取代基以良好的
化学和由外消旋2-羟基醛的转酮酶-催化反应动力学拆分良好的光学收率与
锂羟基丙酮酸得到4,其中只对映异构体(R)-3与5-脱氧-
D-木酮糖5反应。
