Chemo-enzymatic synthesis of N-(4-(Amino (imino) -methyl) benzyl) -2-((R)-4-benzyl-3-oxo-morpholin-2-yl)-acetamide(酶促-化学法合成(R)-N-苄基吗啉-3-酮-2-乙酰(4-脒基)苄胺)

报道了一种酶促-化学法合成光学纯吗啉酮凝血酶抑制剂的新途径.以马来酸酐和氨基醇为起始原料,一锅法合成N-苄基吗啉-3-酮-2-乙酸甲酯;再用脂肪酶CAL-B在甲基叔丁基醚/水(体积分数=1/9)混合溶剂中将其选择性水解,制备光学纯(R)-N-苄基吗啉-3-酮-2-乙酸;经过酰胺化、还原/胺解,得到(R)-N-苄基吗啉-3-酮-2-乙酰(4-脒基)苄胺;所得化合物结构经IR,1H NMR,13C NMR表征确证.文中还讨论了酶源、溶剂、含水量、反应时间等因素对水解拆分的影响....
