We developed a cationic iron(III) salt initiator for radical cation‐induced [4+2] cycloaddition. Fe(OTf)₃ [or Fe(ClO₄)₃] behaves as a highly active oxidant for both electron‐deficient and electron‐rich dienophiles. The scope of substrates is much broader than with FeCl₃ reported previously. With highly active Fe(OTf)₃, we demonstrate a formal total synthesis of Heitziamide A.

阳离子铁（III）盐作为自由基引发的[4 + 2]环加成反应的引发剂

我们开发了一种阳离子铁（III）盐引发剂，用于自由基阳离子诱导的[4 + 2]环加成反应。Fe（OTf）₃ [或Fe（ClO ₄）₃ ]对缺电子和富电子的亲二烯体均起着高活性氧化剂的作用。基材的范围比以前报道的FeCl ₃广泛得多。具有高活性的Fe（OTf）₃，我们证明了Heitziamide A的正式全合成。
