Cationic Iron(III) Salt as an Initiator for Radical Cation-induced [4+2] Cycloaddition

Takahiro Horibe, Shuhei Ohmura, Kei Katagiri, Kazuaki Ishihara

Asian Journal of Organic Chemistry 9 巻 ( 3 ) 頁： 395 - 398 2020年3月

記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：Wiley-VCH Verlag

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.
