By applying a simple TiO2-(NH4)(2)S2O8 system and promoted by UV light, the three-component reactions of cyclic ether, aniline and aldehyde can be progressed efficiently. 29 substituted amines with different structures were synthesized with up to 97% isolated yields. Isotope effect study revealed that the rate-determining step might be the nucleophilic addition step but not radical generation. (C) 2013 Elsevier Ltd. All rights reserved.

on the development of a broadly applicable strategy for the alkylation of in situ formed imines for the construction of functionalized secondary amines under mild reaction conditions. This atom economic transformation exploits the intrinsic electrophilicity of imines towards radical addition, and the fine-tuning of electronic properties of the starting materials allows the formation of a wide variety
