An efficient and high-yielding protocol using nano-ZnO (50–100 nm) as an efficient heterogeneous catalyst for one-pot three-component synthesis of pharmacologically significant furanone derivatives by the condensation of aromatic aldehyde, amine and dimethylacetylenedicarboxylate has been developed. Since the catalyst is heterogeneous, it can be easily separated and recycled several times without much
A simple, efficient, and environmentally benign protocol for the synthesis of 3,4,5-substituted furan-2(5H)-ones has been achieved using extract of watermelon as a natural catalyst. We found, for the first time, that the extract of watermelon could effectively catalyze The condensation reaction of aldehydes, amines, and dialkyl acetylenedicarboxylates to 3,4,5-substituted furan-2(5H)-ones in excellent

3,4,5-substituted furan-2(5H)-ones were One-Pot Multi-Component synthesized by the reaction of aldehydes,
amines and dialkyl acetylenedicarboxylates using silica gel-supported polyphosphoric acid (PPA/SiO2) at room temperature.
This reaction provides a convenient and efficient synthetic method of furan-2(5H)-one derivatives, and also reusability
of catalyst.
Abstract The three-component condensation reaction of aldehydes, amines,and dialkyl acetylenedicarboxylates was conducted, leading to the production of 3,4,5-substituted furan-2(5H)-ones. This reaction is performed in the presence of acetic acid as a cheap and readily available catalyst at room temperature. Graphical Abstract

AbstractAn easy and rapid method for the synthesis of 3,4,5-substituted furan-2 (5H)-ones has been achieved through a three-component reaction of aniline, dialkyl acetylenedicarboxylate, and aromatic aldehydes using nanosilica-tethered polyhedral oligomeric silsesquioxanes with eight branches of 3-aminopropyltriethoxysilane as catalyst under ultrasonic irradiations. We reported a class of organic–inorganic
