    The present invention provides a new and efficient process for the preparation of the dexmethylphenidate hydrochloride with high optical purity, the process comprising: (a) reacting a solution of threo-N-Boc-ritalinic acid with (S)-1-phenylethylamine, separating precipitated solid salt of (R,R)-enriched N-Boc-ritalinic acid with (S)-1-phenylethylamnine from the reaction mixture and recrystallizing, reslurring and/or trituring of said salt; (b) mixing the solid salt of (R,R)-N-Boc-ritalinic acid and (S)-1-phenylethylamine obtained in step (a) with aqueous acid and separating (R,R)-N-Boc-ritalinic acid from the mixture; and (c) reacting the (R,R)-N-Boc-ritalinic acid prepared in step (b) with hydrogen chloride and methanol to give dexmethylphenidate hydrochloride with optical purity of at least 99% ee. The present invention further provides salt of (R,R)-N-Boc-ritalinic acid with (S)-1-phenylethylamine as new intermediate in the preparation of dexmethylphenidate hydrochloride.
    本发明提供了一种新的高光学纯度地地辛美非特酯盐的制备方法,该方法包括:(a)将threo-N-Boc-利他林酸的溶液与(S)-1-苯乙胺反应,从反应混合物中分离出(R,R)-富集的N-Boc-利他林酸的沉淀固体盐和(S)-1-苯乙胺,再结晶、重悬浸和/或研磨该盐;(b)将步骤(a)中得到的(R,R)-N-Boc-利他林酸固体盐与(S)-1-苯乙胺混合后,加入水酸进行混合,然后从混合物中分离出(R,R)-N-Boc-利他林酸;(c)将步骤(b)中制备的(R,R)-N-Boc-利他林酸与氯化氢和甲醇反应,得到光学纯度至少为99% ee的地地辛美非特酯盐。本发明还提供了(R,R)-N-Boc-利他林酸与(S)-1-苯乙胺的盐作为地地辛美非特酯盐制备的新中间体。

    日期:2007.7
    In the synthesis of (2R,2′R)-threo-(+)-methylphenidate, a ring-closing metathesis approach was adopted to construct the ­piperidine ring, while Sharpless asymmetric epoxidation was used for the efficient generation of two contiguous stereocenters.
    在合成(2R,2′R)-threo-(+)-methylphenidate 的过程中,采用了闭环偏析法来构建哌啶环,同时使用 Sharpless 不对称环氧化法来高效生成两个连续的立体中心。

    preparation of four stereoisomers of dexmethylphenidate hydrochloride starting from a single reactant, 2-benzyolpyridine, through an eight-step reaction process, which includes hydrogenation, protection, oxidation, chiral separation, Wittig reaction, hydroboration, pyridinium dichromate oxidation, and methyl esterification. The absolute configuration of the two chiral centers of each stereoisomer was confirmed

    were derived from l-pipecolic acid in 96% optical purity. The versatility of this methodology is demonstrated with the synthesis of the (2R,2'R) and (2S,2'S) enantiomers of p-bromo and p-methoxy derivatives in similar yields and enantiomeric purities. Comparative neurochemical assessments of these synthesized enantiomers at purported dopamine, norepinephrine, and serotonin uptake sites along with locomotor
    我们报道了哌醋甲酯(1)的单个对映异构体的首次不对称合成。从d-哌醇酸中获得1的(2R,2'R)和(2S,2'R)对映体,光学纯度> 99%,而1的(2S,2'S)和(2R,2'S)对映体为衍生自l-哌酸,光学纯度为96%。通过以相似的产率和对映体纯度合成对溴和对甲氧基衍生物的(2R,2'R)和(2S,2'S)对映异构体,证明了该方法的多功能性。这些合成的对映异构体在据称的多巴胺,去甲肾上腺素和5-羟色胺摄取位点的比较神经化学评估以及在大鼠中的运动活性研究也得到了报道。
