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

Rate constants for reactions of octyl radical with its N-hydroxypyridine-2-thione ester precursor were determined using the reduction of octyl radical by n-Bu SnH as a competition reaction. 3 The use of radical cyclization and functionalization steps in organic synthesis is becoming increasingly p
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.
