s was developed by a Tf2O-promoted tandem annulation from phenylethanols and nitriles. Its success was mainly due to the fact that a phenonium ion was formed in the process and practically functioned as a stable and reactive primary phenylethyl carbocation.
一种由Tf 2 O促进的由
苯乙醇和腈进行的串联环化反应,开发了Bischler-Napieralski型合成
3,4-二氢异喹啉的新方法。它的成功主要是由于在该过程中形成了ion离子,并且实际上起了稳定和反应性的伯苯基乙基碳正离子的作用。
