The α-glucosidase inhibitor 1,4-dideoxy-1,4-imino-D-arabinitol (DAB-1) 8 is synthesised in ten steps from D-serine with an overall yield of 49%; the key step of this synthesis makes use of the readily prepared serine-derived α-dibenzylamino aldehyde 3 in a highly diastereoselective glycolate aldol reaction.
α-葡萄糖苷酶抑制剂1,4-去氧-1,4-亚硫酰-D-阿拉伯糖醇(DAB-1) 8是通过十个步骤从D-丝氨酸合成的,整体收率为49%;该合成的关键步骤利用了易于制备的丝氨酸衍生物α-二苄氨基醛3,在高度的非对映选择性醇酸醛缩反应中进行。
