ChemInform Abstract: Intramolecular Free Radical Cyclizations onto Enol Ethers. A General Synthesis of α‐Alkyl‐β‐oxy‐ and α‐Methylene‐β‐oxy‐γ‐butyrolactones.

Abstract

AbstractRadical cyclization of the enol ether bromoacetal (I) yields the cyclic acetal (II), which undergoes Jones oxidation to give the lactone (III), whose X‐ray structure is reported (space group P1, Z=2).
