γ-N,N-Dibenzylamino α,β-dehydro N-formylamino acid esters of type 2 undergo a dyatropic thermal rearrangement in refluxing toluene to yield the isomeric urea derivatives 3. Evidence for a dissociation-recombination mechanism is presented.
在回流的甲苯中,类型2的γ-N,N-二苄氨基α,β-脱氢N-甲酰基氨基酸酯发生二次热重排,生成异构体尿素衍生物3。提出了解离重组机制的证据。
