A continued study of the recently discovered diazotizative allylation (DiazAll) reaction of aniline derivatives is reported. Several allyl reagents, commonly used in radical allylation reactions, were evaluated, and some of these reagents resulted in allylation when used in the DiazAll reaction. The best result was obtained with allyl bromide. Substituted allylic bromides gave the corresponding allyl
据报道,对最近发现的苯胺衍生物的重氮化烯丙基化(DiazAll)反应的持续研究。评估了几种通常在自由基烯丙基化反应中使用的烯丙基试剂,其中某些试剂在DiazAll反应中使用时会导致烯丙基化。用烯丙基溴可获得最佳结果。取代的烯丙基溴化物以不良或优异的产率得到相应的烯丙基芳族化合物。与已建立的芳族烯丙基化方法相比,DiazAll反应表现良好,当使用更复杂的烯丙基溴化物时,效果更好。最后,证实了新的烯丙基化-溴环化反应,并将其用于已知的苯乙醇胺N-甲基转移酶(PNMT)抑制剂的合成,该酶参与肾上腺素的生物合成。
