Homogenous palladium catalyzed intramolecular hydroarylation of appropiately functionalized ortho-iodophenoxyfuranones afforded ABC substructures of AFM1 and austocystine. The o,o′-diiodine effect, coupled with an appropiate urethane tether, allowed regio-controlled annulations.
均相钯催化适当官能化的邻碘苯氧基呋喃酮的分子内氢芳基化反应提供了AFM 1和Austocystine的ABC亚结构。o,o'-二碘的作用,加上适当的氨基甲酸酯系链,可实现区域控制的环行。
