Synthesis of 6-hydroxy-5,5-dialkyl substituted cyclohexenones via(bistrifluoroacetoxyiodo)benzene mediated cyclization of 1,3-dithiane and ethyl enol ether
Abstract
A novel type of intramolecular aldol reaction of 1,3-dithiane and ethyl enol ethers in the same molecule mediated by (bistrifluoroacetoxyiodo)benzene was used for synthesis of 6-hydroxy-5,5-dialkyl substituted cyclohexenones.
