Use of green and biodegradablecatalyst 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 naturalcatalyst 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
3,4,5-Substituted furan-2(5H)-one derivatives were synthesized by using beta-cyclodextrin as a catalyst in water via biomimetic approach. beta-Cyclodextrin can be recovered and reused. (C) 2009 Elsevier Ltd. All rights reserved.
