研究了脱羧、脱质子化生成的不稳定的甲亚胺叶立德与（E）-2-芳亚甲基-1-四氢萘酮的环加成反应。高度的区域选择性已被观察到在一类新的功能化双螺杂环化合物的合成轴承四氢萘酮，苊醌和羟吲哚框架。
The cycloaddition reaction of non-stabilized azomethine ylides, generated through decarboxylation and deprotonation, with (E)-2-arylidene-1-tetralones as dipolarophile has been investigated. A high degree of regioselectivity has been observed in the synthesis of a new class of functionalised dispiroheterocyclic compounds bearing a tetralone, acenapthenequinone and oxindole framework.
