摘要
2-苯乙醇经氯代、傅-克酰化反应后与2-乙酰胺基丙二酸二乙酯(DEAM)反应得2-[2-(4-正辛酰基苯基)乙基]-2-乙酰胺基丙二酸二乙酯,再依次经Et3SiH/AlCl3和NaBH4/CaCl2还原得2-[2-(4-正辛基苯基)乙基]-2-乙酰胺基-1,3-丙二醇,最后经氢氧化锂水解、成盐得新型免疫抑制剂盐酸芬戈莫德,总收率约25%。
Fingolimod hydrochloride was synthesized from 2-phenylethanol via chlorination, Friedel-Crafts acylation and condensation with DEAM to give diethyl 2-acetamido-2-[2-(4-octanoylphenyl)ethyl]malonate(5), which was subjected to successive reduction by Et3SiH/AlCl3 and NaHB4/CaCl2, followed by hydrolysis and salt formation with an overall yield of about 25%.
