DDQ-promoted dehydrogenation from natural rigid polycyclic acids or flexible alkyl acids to generate lactones by a radical ion mechanism
A novel and facile DDQ-mediated dehydrogenationfrom natural rigid polycyclic acids or flexible alkyl acids to generate lactones is described. The formation of lactones proceeds by a radical ion mechanism, which has been established by DPPH -mediated chemical identification, ESR spectroscopy and an enol intermediate trapping.
