摘要：

With styrenes, norbornenes, and cyclopentadiene, 2-ethoxy-3-methylisoquinolinium ion and its 5-nitro derivative undergo polar cycloaddition more readily than do their 2-methyl counterparts. Characteristic of these cycloadditions is a stereoselectivity which in many instances is 100% and which in nearly all instances is believed to have a polar origin. © 1979, American Chemical Society.
