23-Dichloro-56-dicyano-14-benzoquinone (DDQ)-Catalyzed Reactions Employing MnO2 as a Stoichiometric Oxidant

摘要

Several oxidative reactions can be effected with MnO2 in the presence of sub-stoichiometric quantities of DDQ. These transformations include oxidative cyclization, deprotection, and dehydrogenation reactions. The use of MnO2 as a terminal oxidant for DDQ-mediated reactions is attractive based on economical and environmental factors.
