反応手順
A solution of tert-butyl hexahydropyrrolo[3,4-b]pyrrole-5(1H)-carboxylate (424 mg, 2 mmol), N-(9-fluorenylmethoxycarbonyloxy) succinimide (600 mg, 1.8 mmol) and DIPEA (310 mg, 2.4 mmol) in dioxane (20 mL) was stirred at room temperature overnight and then concentrated in vacuo. The residue was treated with EtOAc/H2O, separated, and the aqueous layer was extracted with EtOAc. The combined extracts were washed with brine, dried over Na2SO4, filtered, and concentrated to give the title compound. MS (m/z): 355 (M-boc+H)+.
