摘要
为控制消旋卡多曲产品质量,制备了可能的6种有关物质:[(3-巯基-2-苄基丙酰基)氨基]乙酸(B)、[(3-乙酰巯基-2-苄基丙酰基)氨基]乙酸(C)、5,10-二苄基-4,11-二氧代-7,8-二硫基-3,12-二氮杂十四烷二酸(D)、2-[(2-苄基丙烯酰基)氨基]乙酸苄酯(F)、2-[(3-巯基-2-苄基丙酰基)氨基]乙酸苄酯(G)和5,10-二苄基-4,11-二氧代-7,8-二硫基-3,12-二氮杂十四烷二酸二苄酯(H),并经MS、1H NMR确证结构。
To perform the quality control of racecadotril, six related substances were synthesized, and their structures were confirmed by MS and 1H NMR. These substances were [ (2-benzyl-3-mercaptopropanoyl) amino] acetic acid (B), E (3-acetylthio-2-benzylpropanoyl] amino] acetic acid (C), 5,10-dibenzyl-4,11-dioxo-7,8-dithia-3,12- diazatetradecanedioic acid (D), benzyl 2-(2-benzylacrylamido)acetate (F), benzyl 2-(2-benzyl-3-mercap- topropanamido) acetate (G) and dibenzyl 5,10-dibenzyl-4,11-dioxo-7,8-dithia-3,12-diazatetradecanedioate (H).
