A general stereocontrolled approach for entry into a family of highly biologically active 2,5-diaryl-3,4-disubstituted furano lignans has been developed. The key step involves a diastereoselective aldol-type condensation of an ester enolate having an a-chiral center with an aromatic aldehyde. The me
