Radical Cascade Reaction with 1,4-Dienes and 1,4-Enynes Using 2-(lodomethyl)cyclopropane-1,1-dicarboxylate as a Homoallyl Radical Precursor: One-Step Synthesis of Bicyclo[3.3.0]octane Derivatives

摘要

Radical cascade reaction with various 1,4-dienes and 1,4-enynes using dimethyl 2-(iodomethyl)cyclopropane-1,1-dicarboxylate as a homoallyl radical precursor smoothly proceeds through an iodine atom transfer mechanism to give functionalized bicyclo[3.3.0]octane derivatives in good yields.
