Radical [3 + 2] Cycloaddition Reaction with Various Alkenes Using Iodomethylcyclopropane Derivatives as New Homoallyl Radical Precursors

Abstract

Radical iodine atom transfer [3 + 2] cycloaddition with various alkenes using dimethyl 2-(iodomethyl)cyclopropane-1,1-dicarboxylate and 1,1-bis(phenylsulfonyl)-2-(iodomethyl)cyclopropane as new precursors of a homoallyl radical species smoothly proceeds to give functionalized cyclopentane derivatives in good yields.
