Fmoc-Pro-OH

Description

Fmoc-Pro-OH is easily dissolved in DMF or NMP. Proline fails to produce a blue-to purple color in the Kaiser test. The Isatin test may be used to test the completion of couplings to proline residues.

Chemical properties

white to light yellow crystal powder.

The Uses of Fmoc-Pro-OH

L-Proline-N-Fmoc is N-Fmoc protected L-Proline (P755995) which is an amino acid and precursor (with vitamin C) for collagen, the building block of the structure of tendons, ligaments, arteries, veins and muscles. It is important in wound healing.

Preparation

To a solution of (S)-pyrrolidine-2-carboxylic acid (1 g, 8.7 mmol) in 1,4-dioxane (4 mL) and water (15 mL), K2CO3 (3.24 g, 23 mmol) was added, followed by the addition of 9-fluorenylmethyl chloroformate (2.3 g, 8.3 mmol). The resulting mixture was stirred overnight at room temperature and then treated with water (10 mL). The resulting mixture was extracted with diethyl ether (2 x 20 mL), and the aqueous phase was made acidic with 1M HCl to a pH of 2-3, followed by extraction with dichloromethane (3 x 50 mL). The combined organic layers were dried using anhydrous sodium sulfate and concentrated to yield Fmoc-Pro-OH as a white solid in a 95% yield (2.8 g).
