N-Boc-L-glutamic Acid α-Methyl Ester is a glutamate derivative that undergoes vitamin K-dependent carboxylation in liver microsomes. | [Synthesis]
The general procedure for the synthesis of (S)-4-((tert-butoxycarbonyl)amino)-5-methoxy-5-oxopentanoic acid from methyl (S)-5-benzyl-2-((tert-butoxycarbonyl)amino)pentanedioate was as follows: methyl (S)-5-benzyl-2-((tert-butoxycarbonyl)amino)pentanedioate (4.95 g, 14.09 mmol) was dissolved in 50 mL of a round bottom flask of methanol (20 mL) and 10% palladium/carbon catalyst was added under nitrogen protection. Subsequently, the reaction vessel was purged three times with nitrogen and hydrogen alternately. The reaction mixture was stirred for 6 hours under hydrogen atmosphere and atmospheric pressure. Upon completion of the reaction, the catalyst was removed by filtration and the filtrate was concentrated to afford the target compound (S)-4-((tert-butoxycarbonyl)amino)-5-methoxy-5-oxopentanoic acid as a colorless gelatinous liquid (3.5 g, 96% yield). The specific optical rotation of the product [α]21D = +7 (c 0.1, CHCl3).
