| Description |
1630-1636
A simple, highly efficient, environmentally benign synthesis of bis(indolyl)methanes and bis(indolyl)glycoconjugate by electrophilic substitution reaction of indole or methylindoles with a variety of aldehydes or simple ketones catalysed by 5 mol% of camphor sulphonic acid (CSA) or zirconium oxychloride octahydrate (ZrOCl<sub>2</sub>.8H<sub>2</sub>O) in aqueous medium (20% EtOH-H<sub>2</sub>O) at ambient temperature is reported. The reactions also proceed efficiently with recovered catalyst (CSA or ZrOCl<sub>2</sub>.8H<sub>2</sub>O) and under scale-up condition. |
