The present invention relates to a novel method for producing a compound of the formula [11]
1
wherein R is an optionally substituted aromatic hydrocarbon group, an optionally substituted alicyclic hydrocarbon group, an optionally substituted heterocyclic group or an optionally substituted condensed heterocyclic group, which is useful as a therapeutic agent for diabetes. The method of the present invention is an industrially utilizable method that enables efficient production of the objective compound [11] from &bgr;-methyl L-aspartate via an important intermediate compound [6]
2
wherein R is as defined above, at high yield.
本发明涉及一种新的方法,用于生产化合物的公式[11]1,其中R是一种可选取的取代芳香族烃基、可选取的取代脂环烃基、可选取的取代杂环基或可选取的取代紧缩杂环基,该化合物可用作治疗糖尿病的治疗剂。本发明的方法是一种工业上可利用的方法,能够高产地从&bgr;-甲基L-天冬氨酸经由重要的中间化合物[6]2,其中R如上所定义,高效地生产目标化合物[11]。
