2,5,6,7-Tetrahydro-4H-isoindol-4-one 7a. To a solution of p-toluenesulfonylmethyl isocyanide (TOSMIC) (8g, 0.04mol) in dry THF (50mL), 2-cyclohexen-1-one (4.92mL, 0.04mol) was added at room temperature, followed by the dropwise addition of a solution of t-BuOK (5,5g, 0.49mol) in the same solvent (50mL). After 1h stirring at room temperature water was added and the solution was extracted with ethyl acetate. The organic extracts were dried (Na2SO4) and evaporated under reduced pressure. The residue was purified by chromatography using dichloromethane:ethyl acetate (9:1) as eluant. Pale brown oil; yield 85%.
