Organocatalytic Allylic Amination of Morita-Baylis-Hillman Carbonates
An organocatalytic asymmetric allylic amination of Morita-Baylis-Hillman carbonates with aromatic amines in the presence of -isocupreidine is described. Chiral allylic amines were obtained in almost quantitative yields (90-96%) with moderate enantioselectivity. Recrystallization afforded products in good yields (45-73%) and high optical purity (82-99% ee). This method provides a facile and efficient route to obtain optically active -lactams, including the building block of the cholesterol-lowering drug Ezetimibe.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 26544-38-7, you can contact me at any time and look forward to more communication. Application In Synthesis of 3-(Dodec-2-en-1-yl)dihydrofuran-2,5-dione.
