A modular, stereoselective synthesis of E-3-(arylidene)-5-(alkyl/aryl)-2(3H)-furanones was developed. The methodology features regioselective addition of β-aryl acrylic acids to iodoacetylenes to furnish the Z-acyloxy iodoalkenes. A stereoselective 5-exo-trig Mizoroki-Heck reaction of the acyloxy iodoalkenes generates the target E-2(3H)-furanones. The approach was applied in a formal synthesis of the naturally occurring kinase inhibitor BE-23372M.
