An industrial process for producing hydroxyaldehydes efficiently, by solving the problems of conventional DERA, such as low stability against aldehydes, low catalytic activity for aldol condensation, and the difficulty of controlling the number of acetaldehyde molecules to be condensed, is provided.
According to the process, aldol condensation of a substituted or unsubstituted aliphatic aldehyde compound having 2 to 6 carbon atoms with acetaldehyde is conducted by using D-2-deoxyribose-5-phosphate aldolase which is highly stable against aldehydes and has high catalytic activity for aldol condensation, whereby a hydroxyaldehyde compound having the number of carbon atoms increased by two or four can be produced.
一种工业生产羟基醛的方法,有效解决了传统的DERA存在的问题,如对
醛类的稳定性低、醛缩反应的催化活性低以及难以控制要缩合的
乙醛分子数等问题。根据该方法,使用高度稳定且对醛缩反应具有高催化活性的
D-2-脱氧核糖-5-
磷酸醛缩酶,对具有2到6个碳原子的取代或未取代的脂肪族醛化合物与
乙醛进行醛缩反应,从而可以生产出碳原子数增加两个或四个的羟基醛化合物。
