    申请人:Zhang Hesheng
    公开号:US20070072905A1
    公开(公告)日:2007-03-29
    A process for producing a Donepezil derivative represented by the formula (I), wherein R 1 , R 2 , R 3 , and R 4 each independently represents H, F, an alkyl having from 1 to 4 carbon atoms, or an alkoxy having from 1 to 4 carbon atoms; R 5 represents a phenyl or a substituted phenyl; and n is an integer from 0 to 2, characterized in that the process comprises: (a) a reaction of 4-pyridinecarboxaldehyde with a compound of formula (II) in the presence of a strong acid HX to form a compound of formula (III); (b) a catalytic hydrogenation of a compound of formula (III) or a compound of formula (V) to yield a compound of formula (IV); and (c) an alkylation reaction of a compound of formula (IV) to yield a compound of formula (I).
    一种生产Donepezil衍生物的方法,该衍生物由式(I)表示,其中R1,R2,R3和R4分别独立地表示H,F,具有1至4个碳原子的烷基或具有1至4个碳原子的烷氧基; R5表示苯或取代苯; n是0至2的整数,其特征在于该方法包括:(a)4-吡啶甲醛与式(II)化合物在强酸HX存在下反应,形成式(III)化合物; (b)式(III)化合物或式(V)化合物的催化氢化,得到式(IV)化合物; (c)式(IV)化合物的烷基化反应,得到式(I)化合物。

    The present invention relates to a new process for the preparation of acetylcholinesterase inhibitors of formula (I) or a salt thereof, wherein: R1 is N-acyl-4-piperidyl; N-alkoxycarbonyl-4-piperidyl; 4-piperidyl; N-alkyl-4-piperidyl; N-benzyl-4-piperidyl; N-(φ-aralkyl)-4-piperidyl; 4-pyridyl; R?4, R5, R6 and R7¿ are identical or different and each represents hydrogen, straight-chain or branched alkyl, aryl, hydroxy, alkoxy, aryloxy, benzyloxy, acyloxy, alkylthio, arylthio, benzylthio, acylamino, phthalimido or halogen; n is 1, 2 or 3; m is 1, 2, 3, 4 or 5. This process comprises cyclisation of a compound of formula (II) or salts thereof, wherein R?1, R4, R5, R6 and R7¿, m and n are as defined above; R2 is selected from a derivatised or non-derivatised carboxyl, cyano, N-substituted aminocarbonyl groups or hydrogen; R3 is selected from a derivatised or non-derivatised carboxyl, cyano or N-substituted aminocarbonyl groups, optionally in the presence of acids and/or solvents. One of the most potent acetylcholinesterase inhibitors of the class of compounds prepared according to the present invention is donepezil.
  • Can Heteroarenes/Arenes Be Hydrogenated Over Catalytic Pd/C Under Ambient Conditions?
    作者:Nao Tanaka、Toyonobu Usuki
    DOI:10.1002/ejoc.202000695
    日期:2020.9.14
    Pd/C‐mediated dearomatic hydrogenation under ambient conditions such as balloon pressure and room temperature can be a powerful tool for constructing alicyclic skeletons. Density functional theory calculations have been performed to confirm the mechanistic aspects and the utility of the established methodology has been demonstrated by donepezil synthesis.
    在诸如气球压力和室温等环境条件下,Pd / C介导的脱芳香族氢化反应可能是构建脂环族骨架的强大工具。已经进行了密度泛函理论计算以确认机理方面,并且通过多奈哌齐合成证明了所建立方法的实用性。
