The first example of optically active compound 3c which possesses axial chirality based on the N(open-chain imide)-Ar bond rotation, is described. Furthermore, a quite interesting result is also described, namely, that 3a bearing a bulky acyl group rather than a small one racemized more rapidly. To

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
