The present invention relates to a process for the preparation of β-amino acids and derivatives thereof, which is especially suited for gliptins and particularly sitagliptin. A key step makes use of suitably derivatized epoxides or aziridines, which owing to a chirality provides a source of chirality for intermediates which are suitable for building up β-amino acids and similar compounds, in particular in the construction of the sitagliptin molecule.
本发明涉及一种制备β-氨基酸及其衍生物的方法,该方法特别适用于格列酮类药物,尤其是西他列汀。关键步骤利用适当衍生的环氧化物或氮杂环丙烷,由于手性而为中间体提供手性来源,适用于构建β-氨基酸和类似化合物,特别是在构建西他列汀分子时。
