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.

E -3-（芳基亚甲基）-5-（烷基/芳基）-2（3 H）-呋喃酮的立体选择性合成通过碘代炔烃的连续氢酰氧基化-Mizoroki-Heck反应

开发了模块化的E -3-（亚芳基）-5-（烷基/芳基）-2（3 H）-呋喃酮的立体选择性合成方法。该方法的特征在于将β-芳基丙烯酸的区域选择性加成到碘乙炔中以提供Z-酰氧基碘烯烃。酰氧基碘代烯烃的立体选择性5 -exo-trig Mizoroki-Heck反应生成目标E -2（3 H）-呋喃酮。该方法被用于天然存在的激酶抑制剂BE-23372M的正式合成中。
