YieldReaction ConditionsOperation in experiment
96%
Stage #1: at 0℃;
Stage #2: With acetic acid In methanol; hexanes; toluene
1-BENZYLOXYCARBONYL-3-AZETIDINECARBOXYLIC acid (from step (i); 9.3g, 39. 6MMOL) was dissolved in methanol (LOOML) and toluene (100mL), and cooled to 0°C. A solution of 2M trimethylsilyldiazomethane in hexanes was then added dropwise until bubbling had ceased and the yellow colour persisted. Acetic acid was then added dropwise until the yellow colour disappeared. Concentration of the solution yielded the title compound as an oil (9.48G, 38mmol, 96percent). IH NMR (400MHZ, CDC13) : 8 7.36-7. 31 (5H, m), 5.10 (2H, s), 4.19 (4H, D, J7. 8Hz), 3.75 (3H, s), 3.39 (1H, quintet, J 7. 8HZ).

YieldReaction ConditionsOperation in experiment
98% at 20℃; for 4 h; EXAMPLE 27B; 1-benzyl 3-methylazetidine-1,3-dicarboxylate A solution of Example 27A (4.8 g, 20.3 mmol) in ether (100 ml) was treated with diazomethane (100 ml in ether, 60 mmol) at room temperature for 4 hours. Removal of the volatiles gave Example 27B (4.8 g Yield: 98percent). MS (DCI/NH3) m/z 250 (M+H)+.
