Mn(OAc)3 -: an efficient oxidant for regeneration of DDQ:: deprotection of p-methoxy benzyl ethers

Mn(OAc)(3) has been successfully developed as a new oxidant for the regeneration of DDQ from HDDQ. This DDQ regeneration technique, making use of 3 equiv. of Mn(OAc)(3)-DDQ (10 mol%), was applied to the deprotection of p-methoxy benzyl (PMB) ethers. (C) 2000 Elsevier Science Ltd.
