Et3N as a catalyst for the synthesis of indeno[1,2-b]chromene derivatives via three-component condensation reaction

Functionalized indeno[1,2-b]chromene derivatives have been synthesized via condensation reaction of 1H-indene-1,3(2H)-dione with benzaldehyde and cyclization with 2-hydroxynaphthalene-1,4-dione in the presence of a catalytic amount of triethylamine (Et3N) in EtOH at room temperature. It was observed that benzaldehyde bearing electron donating group gave high yield of product, whereas, benzaldeh...

Hydroxy sodalite zeolite as a recyclable catalyst for the green synthesis of tetrahydrobenzo[b]pyrans via one-pot three-component condensation reaction

The utilization of hydroxy sodalite (H-SOD) as catalyst under solvent-free condition is described for the efficient preparation of tetrahydrobenzo[b]pyrans. These compounds are synthesized by three-component reactions of aldehydes, alkylnitriles and dimedone. H-SOD that is the waste-product of zeolite manufacturing process is used as an efficient and a very inexpensive catalyst. Furthermore, it...
