Alkoxycarbonyloxy radicals from ally1 and homoallyl alcohols cyclize in an exe fashion to give, respectively, 3-substituted 1,Zdiol camonates and 4-substituted 1,3diol carbonates whereas simple alkoxycarbonyloxy radicals add intermolecularly to ethyl vinyl ether to give, ultimately, carbonates of gl
Dialkylaminium cation radicals pmduced from the title precursors add to ethyl vinyl ether to give &amino ethers in good yields. When an ally1 group is present on nitrogen, a cyclization reaction follows the addition, and pyrrolidines ate formed. Simple cyclic enol ethers also can be employed.
