Stabilized α,β:γ,δ-unsaturated azomethine ylides were generated by the deprotonation of isoquinolinium salts. 1,7-Electrocyclization of these dipoles, followed by a 1,5-hydrogen shift, gives tetrahydro[5,6]azepino[2,1-a]isoquinolines.
通过异喹啉鎓盐的去质子化反应生成稳定的α,β:γ,δ不饱和偶氮甲碱。这些偶极的1,7-电环化,然后转移1,5-氢,得到四氢[5,6]氮杂环庚烷[2,1- a ]异喹啉。
