pyrolysis of the oxazines formed from 2-piperidineethanol produced 2,3-dehydropiperidine enamines. The same results were observed when these oxazines were irradiated with microwaves. Various 2-substituted perhydrooxazines were synthesized by allowing 2-piperidineethanol or 2-piperidinemethanol to react with aldehydes or ketones.
由2-哌啶乙醇形成的恶嗪的热解产生了2,3-脱氢哌啶烯胺。当这些恶嗪用微波照射时,观察到相同的结果。通过使2-哌啶乙醇或2-哌啶甲醇与醛或酮反应,合成了各种2-取代的全氢恶嗪。
