Nano-sawdust/Sn(IV) as an Efficient Bio-based Nano-catalyst for the Synthesis of Highly Substituted Dihydro-۲-oxopyrroles

Nano-sawdust/Sn(IV) was used as a readily available, inexpensive, biodegradable and environmentally benign heterogeneous solid acid biocatalyst for the one pot cascade synthesis of highly functionalized dihydro-۲-oxypyrroles. Four-component reactions (۴CRs) of the dialkylacetylenedicarboxylates, amines and aldehydes were used for the synthesis of highly functionalized dihydro-۲-oxypyrroles under thermal conditions.
