31970-04-4, The molecularity of an elementary reaction is the number of molecules that collide during that step in the mechanism. If there is only a single reactant molecule in an elementary reaction, that step is designated as unimolecular.31970-04-4, name is Benzyl 2,5-dihydro-1H-pyrrole-1-carboxylate. A new synthetic method of this compound is introduced below.
To a solution of benzyl 2,5-dihydro-1 H-pyrrole-1-carboxylate (33 g, 163 mmol) in dichloromethane (540 ml_) was added MCPBA (77 wt.%, 44 g) and the reaction mixture was stirred at room temperature for 18 hrs. The mixture was diluted with saturated aqueous sodium carbonate solution (500 ml_) and the resulting mixture was stirred at room temperature for 1 hr. The separated organic layer washed with water and brine, dried over sodium sulfate, filtered off and concentrated under reduced pressure. The residue was purified by column chromatography [silica gel] providing benzyl 6-oxa-3- azabicyclo[3.1.0]hexane-3-carboxylate (29.5 g) as a yellow oil. H NMR (400 MHz, chloroform-d) delta [ppm]: 3.38 (dd, J = 12.8, 6.0 Hz, 2 H), 3.68 (d, J = 3.6 Hz, 2 H), 3.87 (dd, J = 13.2, 19.6, 2 H), 5.1 1 (s, 2 H), 7.33 (m, 5 H). LCMS (m/z): 220.0 [M+H]+; Rt = 0.69 min., 31970-04-4
