New Activation Methods for Imino Compounds and Their Intriguing Reactions
1.Introduction Widespread existence of nitrogen-containing compounds such as amino acids, alkaloids, and functional materials coupled with their use as useful synthons prompted us to explore new activation methods for imino compounds and subsequent intriguing reactions.For the synthesis of nitrogen-containing compounds, addition reactions to, -unsaturated imines constitute one of the most straightforward approaches.However, difficulties are always encountered regarding the regioselectivity.On the other hand,imino compounds do not always have enough electrophilicity as compared with their parent carbonyl counterparts.For the activation of imino carbons,use as iminium salts offers one of the solutions.The following new reactions will be discussed.
