Provided is a process for synthesizing Fingolimod hydrochloride comprising the following steps: (1) reacting a compound (5) with a sulfhydryl compound (I) under alkaline conditions to produce a key intermediate product (6); (2) oxidizing the product (6) to produce a sulfonyl compound (7); (3) carrying out a Knoevenagel condensation reaction of the sulfonyl compound (7) with an aldehyde group compound (8) under alkaline conditions to obtain a key intermediate (9); (4) having the intermediate (9) undergo a hydrogenation reduction and at the same time carrying out an amino deprotection to obtain 5-amino-5-[2-(4-n-octylphenyl)ethyl]-2,2-dimethyl-1,3-dioxane; and then carrying out an acetonylidene deprotection in dilute hydrochloric acid and at the same time salifying to obtain Fingolimod hydrochloride.
提供了一种合成盐酸非吡格列醇的过程,包括以下步骤:(1)在碱性条件下将化合物(5)与巯基化合物(I)反应,制备关键中间体(6);(2)将产物(6)氧化,生成磺酰基化合物(7);(3)在碱性条件下,将磺酰基化合物(7)与醛基化合物(8)进行Knoevenagel缩合反应,得到关键中间体(9);(4)使中间体(9)经历氢化还原反应,同时进行氨基去保护,得到5-氨基-5-[2-(4-正辛基苯基)乙基]-2,2-二甲基-1,3-二氧杂环己烷;然后在稀盐酸中进行丙酮基亚胺去保护,同时盐化,得到盐酸非吡格列醇。
