asymmetric ligation of aliphatic aldehydes to afford enantiomerically enriched 2-hydroxy ketones. Carboligation of linear aldehydes with both enzymes results in high levels of conversion and in enantioselectivities of up to 80 % ee. In cases involving branched aliphatic aldehydes, BAL enables the carboligation of 3-methylbutanal with a high level of conversion and an enantioselectivity of 89 % ee. ((c)
苯甲醛裂解酶 (BAL) 和
苯甲酰甲酸脱羧酶 (BFD) 催化脂肪醛的不对称连接,得到富含对映体的 2-羟基酮。线性醛与两种酶的碳化作用导致高
水平的转化率和高达 80% ee 的对映选择性。在涉及支链脂肪醛的情况下,BAL 能够以高转化率和 89% ee 的对映选择性进行
