Participants

Reaction Steps

(+/−)-Benzyl ((6R,8R,10 S)-8-(3-((benzoxycarbonyl)amino)pyridin-4-yl)-10-methyl-1,4-dioxaspiro[4.5]decan-6-yl)carbamate (1.0 equiv.) was dissolved in MeOH (0.10 M) and degassed with Argon to vacuum. Pd/C (0.05 equiv.) was added and the mixture was stirred under a H2 balloon for 20 hrs. The mixture was filtered and concentrated. The crude and CBZ-OSu (0.99 equiv.) were dissolved in DCM (0.20 M). The reaction was stirred at room temperature for 2 hrs. The solution was diluted with EtOAc and washed with water, dried over sodium sulfate, filtered and concentrated. The crude residue was purified by ISCO chromatography. Purification was completed via SFC (40% EtOH, 15 mL/min, OJ column) to yield benzyl (6S,8S,10R)-8-(3-aminopyridin-4-yl)-10-methyl-1,4-dioxaspiro[4.5]decan-6-ylcarbamate (28% yield, 99% ee) and benzyl (6R,8R,10 S)-8-(3-aminopyridin-4-yl)-10-methyl-1,4-dioxaspiro[4.5]decan-6-ylcarbamate (13% yield, 99% ee). LC/MS (m/z)=398.2 (MH+), Rt=0.64 min.
