Abstract: 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.
