Radical [3+2]-cycloaddition reaction with alkenes using dimethyl 2-(iodomethyl)cyclopropane-1,1-dicarboxylate as a new homoallyl radical precursor

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