Triacetoxyperiodinane → N-[(1-methylindole-2-carbonyl)valinyl]-3-amino-4-oxo-5-fluoropentanoic acid, t-butyl ester

Participants

Reaction Steps

To a solution of N-[(1-methylindole-2-carbonyl)valinyl]-3-amino-4-hydroxy-5-fluoropentanoic acid, t-butyl ester (51 mg, 0.11 mmol) in DMSO(1 mL) was added Dess-Martin periodinane (110 mg). After 30 min at room temperature the reaction mixture was partitioned between ethyl acetate and water. The organic layer was washed with water and brine, dried and concentrated to a white solid. Trituration with diethyl ether and collection of the solid afforded the title compound as a white powder (25 mg, 49% yield). TLC(MeOH:CH2Cl2, 5:95): Rf=0.48.
