The hydroxynitrile lyase from Hevea brasiliensis not only catalyzes – according to the natural activity of this enzyme – the formation and cleavage of cyanohydrins but also the reaction of nitroalkanes with aldehydes (Henry reaction). This is the first example of an enzymatic nitroaldol reaction. With nitromethane and nitroethane a broad range of aldehydes can be transformed into the corresponding
来自巴西橡胶树的羟腈裂解酶不仅根据该酶的自然活性催化氰醇的形成和裂解,而且还催化硝基烷烃与醛的反应(亨利反应)。这是酶促硝基醛醇缩合反应的第一个例子。使用硝基甲烷和硝基乙烷,可以将多种醛转化为相应的硝基醇,产率高达77%,对映体过量(ee)高达99%。
