Participants

Reaction Steps

A mixture of (2S)-1-(1,2-dioxo-3,3-dimethylpentyl)-2-pyrrolidine-carboxylic acid (500 mg; 2.07 mmol), benzyl alcohol (335 mg; 3.10 mmol), dicyclohexylcarbodiimide (683 mg; 3.31 mmol), 4-dimethylaminopyridine (84 mg; 0.69 mmol) and camphorsulphonic acid (160 mg; 0.69 mmol) in methylene chloride (30 mL) was stirred overnight under a nitrogen atmosphere. The reaction mixture was filtered through Celite to remove solids and concentrated in vacuo, and the crude material was purified on a flash column (25% ethyl acetate in hexane) to obtain 680 mg of the product as a colorless oil. 1H NMR (CDCl3; 300 MHz) δ 0.85 (t, 3H); 1.19 (s, 3H); 1.22 (s, 3H); 1.61–2.25 (m, 6H); 3.46–3.56 (m, 2H); 4.58 (dm, 1H); 5.18 (d, 2H, 7.35 (br, 5H).
