On the basis of the reaction of β-styrylmalonates with furfural derivatives in the presence of GaCl3 that occurs with opening of the furan ring, an efficient diastereoselective method for the synthesis of trisubstituted cyclopentenones containing a 1,4-diketone moiety was developed. The regularities of the reaction were studied, and a number of chemical reactions of the resulting substrates were carried out. A mechanism for the formation of substituted (4-oxo-2-arylcyclopent-2-enyl)malonates was suggested.
