31970-04-4, Benzyl 2,5-dihydro-1H-pyrrole-1-carboxylate is a pyrrolines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
A solution OF BENZYL-2, 5-DIHYDRO-LH-PYRROLE-L-CARBOXYLATE (10. OG, 49. 3MMOL) in THF (200mL) was treated with osmium tetroxide solution (2.5percent in TERT-BUTANOL, 5ML) and N-METHYLMORPHOLINE (6.90g, 59. 0MMOL) and the reaction mixture stirred at rt under argon for 72h. Aqueous sodium thiosulfate solution (10percent, 200mL) was added and the mixture stirred for a further lh and then concentrated in vacuo. The resulting aqueous layer was extracted with ethyl acetate (3 x 200mL) and the combined organic layers washed with aqueous sodium thiosulfate solution (10percent, 300mL) and hydrochloric acid (LN, 300mL). The organic fraction was dried (MgS04) and concentrated in vacuo to give the title compound as an off-white solid. ON (CDCl3): 2. 67 (2H, br s), 3.38-3. 45 (2H, m), 3.63-3. 67 (2H, m), 4.22-4. 26 (2H, M), 5.12 (2H, s), 7.30-7. 38 (5H, m); m/z (ES+) = 238 [M+ H] +., 31970-04-4
31970-04-4 Benzyl 2,5-dihydro-1H-pyrrole-1-carboxylate 643471, apyrrolines compound, is more and more widely used in various fields.
