Multi-component synthesis of spiro[4H-indeno[1,2-b] pyridine-4,3′-[3H]indoles] using Zn(BDC) as a metal–organic framework

In this research Zn(BDC) metal–organic framework has been used as a novel, mild and environmentally friendly catalyst for an efficient one-pot synthesis of indole derivatives under solvent free conditions.This method provides a noble and improvedmethod for the synthesis of indoles in terms of excellent yields, short reaction times and little catalyst loading.
