摘要

BF3ano-sawdust was used as a readily available, inexpensive, biodegradable and environmentally benign heterogeneous solid acid catalyst for the one-pot cascade synthesis of highly functionalized dihydro-2-oxypyrroles. Four-component reactions (4CRs) of dialkylacetylenedicarboxylates, primary amines and aldehydes were used for the synthesis of these compounds under thermal conditions.
