An efficient synthesis of α,β-unsaturated alkylimines at low temperature using azides has been developed. Carbocations generated from allyl alcohols helped achieve a rapid conversion under mild conditions with azides to afford reactive α,β-unsaturated imines. Hydroxy or alkoxy groups are essential for these transformations, and utilizing readily accessible allyl alcohols gave a wide extension of substrates
已经开发了使用叠氮化物在低温下高效合成α,β-不饱和烷基亚胺的方法。由烯丙醇产生的碳正离子有助于在温和条件下与叠氮化物实现快速转化,从而提供反应性α,β-不饱和亚胺。羟基或烷氧基对于这些转化是必不可少的,利用容易获得的烯丙醇可广泛扩展底物。这种新方法的效率在亚胺蚁毒生物碱的全合成中得到了证明。
