Abstract
- A recyclable catalyst, β -cyclodextrin-SO 3 H 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. [ABSTRACT FROM AUTHOR]
