The present invention is directed to a process for the preparation of enantiomerically enriched β-amino acid derivatives which are important chiral building blocks and intermediates in pharmaceuticals. More specifically, the invention pertains to a novel process for practically convenient and economically producing enantiomerically enriched β-amino acid derivatives which are useful for the synthesis of amide inhibitors of dipeptidyl peptidase IV like Sitagliptin, which have been used to treat type 2 diabetes.
本发明涉及一种制备对映富集的β-氨基酸衍生物的方法,这些衍生物是重要的手性构建块和药物中间体。更具体地,该发明涉及一种新颖的方法,用于方便实用和经济地生产对映富集的β-氨基酸衍生物,这些衍生物对于合成类似西他列汀的二肽基肽酶IV抑制剂的酰胺具有用处,这些抑制剂已被用于治疗2型糖尿病。
