Intermolecular Visible‐Light Photoredox Atom‐Transfer Radical [3+2]‐Cyclization of 2‐(Iodomethyl)cyclopropane‐1, 1‐dicarboxylate with Alkenes and Alkynes. Issue 36 (31st July 2013) - Gu, Xiangyong
Abstract Radical chemistry! A visible‐light‐promoted, tin/boron‐free intermolecular [3+2] atom‐transfer radical cyclization reaction was developed by using iridium polyphenylpridinyl complex as the sensitizer (see scheme). 2‐(Iodomethyl)cyclopropane‐1, 1‐dicarboxylate reacted with various alkenes and alkynes to form cyclopentane and cyclopentene derivatives.
