Selective oxidations with activated carbon: applications to substrates containing acidic allytic methine and methylene groups
Abstract
Butenoates substituted at the γ-position with an acidifying group, e.g., COR, CO2R, SO2R, and PO(OR)2, undergo a regioselective oxidation (in which a methine group is converted into a carbinol function and a methylene group into a keto moiety) in the presence of activated carbon.
