Treatment of dihydrocubebin (1) with DDQ in acetic acid gives the 2-aryltetrahydrofuran (3) while with DDQ in trifluoroacetic acid it affords the isomeric dibenzocyclooctadiene (5). Treatment of the 3,4-dibenzyltetrahydrofuran (2), obtained by cyclisation of (1), with DDQ in acetic acid gives a mixt
The regiospecific oxidation of alkyl group of both sterically hindered and unhindered aromatic amine to corresponding carbonyl compound was done in aq. medium by using DDQ. The optimized reaction protocol was found to be most simple, high yielding and novel method for oxidation of alkyl group of aro
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.
