Copper-catalyzed Three-Component Annulation Toward Pyrroles Via the Cleavage of Two C-C Bonds in 1,3-Dicarbonyls.
CHEMICAL COMMUNICATIONS(2023)
摘要
The first copper-catalyzed three-component annulation of α,β-unsaturated ketoximes, 1,3-dicarbonyls and paraformaldehyde has been documented. This novel strategy achieved the two C-C bond cleavage of 1,3-dicarbonyl compounds directly as a single-carbon synthon and provided a new and highly efficient method for the synthesis of 2,3-disubstituted pyrroles in moderate to good yields with broad functional group compatibility.
