-
Paragraph 0068-0071, (2019/11/12)
The invention relates to a synthetic process of an anti-hyperglycemic drug intermediate R-3-amino-piperidine dihydrochloride. The synthetic process comprises the steps: using inexpensive L-glutamic acid as a starting material, and performing esterification, amino protection, reduction, hydroxyl protection, substitution, cyclization and removal of protecting groups for amino groups so as to obtainthe R-3-amino-piperidine dihydrochloride. Compared with the prior art, the synthetic process has cheap and easily available raw materials, good selectivity, good atomic economy, high total yield and mild reaction conditions, and is suitable for industrial production.
