Key to success: The title reaction provides facile access to enantioenriched 3,4‐dihydroquinazolin‐2(1H)‐ones containing a quaternary stereogenic center in high yields with excellent enantioselectivities. Subsequent transformations lead to the convenient preparation of the anti‐HIV drug DPC 083 and N‐fused polycyclic compounds without loss of enantiomeric excess.
成功的关键:标题反应可轻松获得富含对映体的3,4-二氢喹唑啉-2(1 H)-,其中一个具有季生立体中心的收率高,对映选择性极好。随后的转化可方便地制备抗HIV药物DPC 083和N融合的多环化合物,而不会损失对映体过量。
