Abstract

Silver(I)-loaded titanium dioxide (AgNO3/TiO2) catalyzes the direct N-methylation of amino acids with methanol under irradiation with UV light. This method produces a variety of N-methyl and N,N-dimethyl amino acids with retention of their optical purity.

Abstract

N-Methylation of amines with methanol proceeds at room temperature in the presence of a silver-loaded titanium dioxide (Ag/TiO2) photocatalyst under UV-vis light irradiation. This method allows facile synthesis/isolation of N-methylamines bearing various functional groups including N-benzyl, N-allyl, N-Boc, hydroxyl, ether, acetal, carboxamide, formamide, and olefin groups.
