A process is described for the preparation of R or S aminocarnitine, R or S phosphonium aminocarnitine and R and S 3,4 diaminobutanoic acid, and their derivatives with the following formula:
1
where Y is as described in the attached description, starting from aspartic acid with the same configuration as the desired compounds. This process is advantageous from the industrial point of view in terms of the type of reactants used, the reduced volumes of solvents and the possibility of avoiding purification of the intermediate products.
本文描述了一种制备R或S氨基肉碱,R或S磷酸氨基肉碱和R和S 3,4-二氨基丁酸及其衍生物的过程,其化学式如下:1其中Y如附加说明所述,从具有所需化合物相同构型的天冬氨酸出发。该过程在工业上具有优势,因为使用的反应物类型、溶剂体积的减少以及避免中间产物的纯化。
