Abstract

Both symmetrical and unsymmetrical 3,4-diaryl-substituted 2(5H)-furanones have been efficiently synthesized using an inexpensive procedure involving the Pd(OAc)2/PCy3-catalyzed Suzuki-type arylation of readily available 3-aryl-4-tosyloxy-2(5H)-furanones as the key step. The mild conditions of this arylation protocol have also been used for the high yielding synthesis of 4-aryl-6-methyl-2(2H)-pyranones from 6-methyl-4-tosyloxy-2(2H)-pyranone.
