Reaktionsschritte
To a round-bottom flask equipped with a stir bar was added (2S,3S)-methyl 2-((tert-butoxycarbonyl)amino)-3-((R)-hex-5-en-2-yloxy)pentanoate (458 mg, 1.39 mmol), THF (5 mL) and MeOH (5 mL). To the stirred solution was added aq. LiOH (2.0 M, 2 mL). The mixture was stirred for 16 h, then was concentrated in vacuo to afford an aqueous solution. The solution was acidified with aq. HCl (1 M) and then transferred to a separatory funnel. The mixture was twice extracted with EtOAc. The combined organics were washed with brine; dried over MgSO4; filtered; then concentrated in vacuo to afford (2S,3S)-2-((tert-butoxycarbonyl)amino)-3-((R)-hex-5-en-2-yloxy)pentanoic acid as a white foam (438 mg, 100%).
