Use of green and biodegradable catalyst in organic synthesis is undeniable. Easy access, inexpensive, natural and green catalysts are valuable. In this study, a green procedure by using pectin as a green and natural catalyst for the one-pot synthesis of dihydro-2-oxopyrroles and 3,4,5-trisubstituted furan-2(5H)-ones at ambient temperature in aqueous media has been developed. This methodology has some advantages such as: use of a hetero polysaccharide as a easy access and biodegradable catalyst, clean work-up and no need to column chromatography.
