Abstract

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-2-oxypyrroles. Four-component reactions (4CRs) of the dialkylacetylenedicarboxylates, amines and aldehydes were used for the synthesis of highly functionalized dihydro-2-oxypyrroles under thermal conditions.
