実験手順
cis-(±)-5-Bromo-1,2,3,3a,8,8a-hexahydro-6-methoxy-1,3a,8-trimethylpyrrolo[2,3-b]indole (11 g) was dissolved in dry DCM (200 ml) and added dropwise at 0° C to a stirred solution of BBr3 in DCM (300 ml). The mixture was warmed to room temperature and stirred overnight under nitrogen. The mixture was quenched with aq. Na2CO3 and aq. NaHCO3 until basic at 0° C. The organic layer was dried and evaporated to a foam (10 g). The IR, NMR and Mass Spectra confumed the purity and identity of this product.
