3-[(4S,5S)-3-benzyloxycarbonyl-4-isobutyl-2,2-dimethyloxazolidin-5-yl]-2-[2-(2-tetrahydropyranyloxy)ethyl]-2-propenoic acid methylamide → (2RS,4S,5S)-5-amino-4-hydroxy-2-[2-(2-tetrahydropyranyloxy)ethyl]-7-methyl-octanoic acid methylamide

Participants

Reaction Steps

29.2 mg of 3-[(4S,5S)-3-benzyloxycarbonyl-4-isobutyl-2,2-dimethyloxazolidin-5-yl]-2-[2-(2-tetrahydropyranyloxy)ethyl]-2-propenoic acid methylamide was dissolved in ethanol and then hydrogenated by using palladium black as a catalyst under atmospheric pressure. The reaction mixture was subjected to filtration, and the solvent of the filtrate was distilled off under reduced pressure to obtain 19.2 mg of (2RS,4S,5S)-5-amino-4-hydroxy-2-[2-(2-tetrahydropyranyloxy)ethyl]-7-methyl-octanoic acid methylamide.
