2-benzyl 3-methyl (2S,3S,5R)-1-benzyl-5-hydroxypiperidine-2,3-dicarboxylate → (2S,3S,5R)-5-hydroxy-3-(methoxycarbonyl)piperidine-2-carboxylic acid

Participants

Reaction Steps

A mixture of 2-benzyl 3-methyl (2S,3S,5R)-1-benzyl-5-hydroxypiperidine-2,3-dicarboxylate (1.00 g, 0.00261 mol) in 10 mL of methanol was hydrogenated in the presence of 10% Pd/C, under a balloon pressure of hydrogen, for 3 h. After filtered off the catalyst, the filtration was concentrated to dry in vacuo and used directly in next step. MS (ESI): (M+H)+=204.0.
