An unprecedented organocatalytic enantioselective [4 + 2] cycloadditionreaction of vinyl quinolines with dienals is achieved with the synergistic activation of CH3SO3H and a chiral aminocatalyst. The power of the process is demonstrated by its high efficiency of the production of new synthetically and biologically valued chiral quinoline architectures in high yields and with excellent enantioselectivities
通过CH 3 SO 3 H和手性氨基催化剂的协同活化,实现了乙烯基喹啉与二烯类化合物的前所未有的有机催化对映选择性[4 + 2]环加成反应。该方法的强大能力以其高效率,高收率和优异的对映选择性生产了具有合成和生物学价值的新型手性喹啉结构而得到证明。
