Enhancement of antioxidant activity of p-alkylaminophenols by alkyl chain elongation

The initial finding that the p-methylaminophenol (6) exhibited antioxidant activity led us to investigate whether the length of alkyl chains linked to the aminophenol residue might affect antioxidative activity. Therefore, we synthesized p-butylaminophenol (5), p-hexylaminophenol (4), p-octylaminophenol (3), and p-methoxybenzylaminophenol (7). All p-alkylaminophenols quenched α,α-diphenyl-β-picrylhydrazyl (DPPH) radicals, with 7 being the most potent DPPH radical scavenger. Lipid peroxidation by rat liver microsomes was reduced by p-alkylaminophenols in dose- and aminophenol alkyl chain length-dependent fashion (3>4>5>6), with 3 being the most potent lipid peroxidation inhibitor, at approximately 350-fold higher potency than 6. These results indicate that elongation of alkyl chains in p-alkylaminophenols may increase antioxidative activity, and that p-alkylaminophenols may potentially be useful in the development of antioxidants.

Use of primary amines for the selective n-alkylation of anilines by a reusable heterogeneous catalyst

Traditionally, anilines can be alkylated with reactive alkyl halides but now more safe reagents such as alcohols or even amines can be used. To overcome the limits of homogeneous catalysis for aniline N-alkylation, we have developed a protocol that employs simple Pd/C as a heterogeneous catalyst under microwave dielectric heating. The process, based on the easy Pd-mediated oxidation of primary amines to imines followed by aniline addition, is characterized by a high atom economy as ammonia is the only other product of the reaction. This kind of aniline alkylation with amines has been carried out both in ionic liquid medium using [bmim]PF6 or in a more traditional solvent such as THF where the catalyst could be successfully recycled more times. The reusability of the catalyst was further confirmed by using material recycled from the amination in a standard alkene hydrogenation without loss of efficiency.

One-pot reductive mono-N-alkylation of aniline and nitroarene derivatives using aldehydes

(Chemical Equation Presented) One-pot reductive mono-N-alkylation of aniline and nitroarene derivatives using various aldehydes by Pd/C catalyst in aqueous 2-propanol solvent with ammonium formate as in situ hydrogen donor is illustrated. The reaction proceeded smoothly and selectively with excellent yield at room temperature. Our protocol presents a facile, economical, and environmentally benign alternative for reductive amination.
