    • General procedure for the synthesis of spiro-cyclopropanooxindoles 2-4, 8 and 9: To an oven-dried flask, a solution containing cyclic diazoamide 1 (1 mmol) and cyclic olefin (1.1 mmol) in dry dichloromethane (50 mL) under inert atmosphere was added 20 mol % of CuOTf or 2.0 mol % of rhodium(II) acetate dimer and stirred for appropriate duration at room temperature. The reaction was monitored by TLC and IR. After the decomposition of all diazoamide, the reaction mixture was evaporated and subjected to 100-200 mesh silica-gel column chromatography (EtOAc/hexane) to afford the respective spiro- cyclopropanooxindoles 2-4, 8 and 9.
