📜γ-Fluoroglutamic Acid Diisopropyl Ester Hydrochloride置于盐酸体系中,化学反应 3.0H,以84%的收率获得4-氟-Dl-谷氨酸 参考文献:Chemistry Of 4-Fluoroglutamic Acid. Part 2. Separation Of The Diastereomers On A Large Scale. Preparation Of Cis-And Trans-4-Fluoro-5-Pyrrolidone-2-Carboxylic Acids (4-Fluoropyroglutamic Acids) 标题:Chemistry Of 4-Fluoroglutamic Acid. Part 2. Separation Of The Diastereomers On A Large Scale. Preparation Of Cis-And Trans-4-Fluoro-5-Pyrrolidone-2-Carboxylic Acids (4-Fluoropyroglutamic Acids) 摘要:Separation Of The 4-Fluoroglutamic Acid Diastereomers Has Been Achieved By Crystallization Of The Hydrochlorides Of Their Dialkyl Esters 1B And 2D. Subsequent Hydrolysis Afforded The Diastereomers 1A And 2A In 100% Steric Purity. Conversion Of The Acids Into The 5-Methyl Esters Followed By Treatment With Ammonia Gives Rise To The Trans And Cis Isomers Of 4-Fluoro-5-Pyrrolidone-2-Carboxylic Acid,3 And 4. NMR Data Are Given.

参考标题:γ-Fluoroglutamic Acid 作者:R. L. Buchanan,F. H. Dean,F. L. M. Pattison |发布日期:1962.8.1 摘要:The Synthesis Of γ-Fluoroglutamic Acid, Hoocchfch2Ch(Nh2)Cooh, Was Achieved By Two Independent Methods, Both Of Which Involved The Michael Reaction: (1) Methyl α-Fluoroacrylate And Diethyl Acetamidomalonate Gave The Transesterified Intermediate, Which On Hydrolysis Produced γ-Fluoroglutamic Acid (31% Yield); (2) Ethyl α-Acetamidoacrylate And Diethyl Fluoromalonate Reacted Under Mild Conditions To Give, After Hydrolysis, The Required Amino Acid In 56% Overall Yield. Of The Two Procedures, The Second Is Preferable, Since It Is Based On More Readily Available Starting Materials And Gives A Higher Yield.
