Abstract
A recyclable catalyst, β-cyclodextrin-SO3H in aqueous medium was used effectively for the synthesis of spiroindolones (tetrahydrospiro-β-carbolines as well as tetrahydrospiro-γ-carbolines) in a Pictet-Spengler spirocyclisation. The products were obtained in good yield in an environmental friendly procedure.
