Abstract
A gold-catalyzed oxidation of arylallenes to form α-diketones and aldehydes in good yields is presented. Further directed synthesis of quinoxalines and benzimidazoles, via the condensation of the resulting α-diketones and aldehydes with benzene-1,2-diamine, was achieved in high yields.
摘要
本文报道了一种金催化的芳基联烯氧化反应，以高产率得到α-二酮和醛。进一步通过所得α-二酮和醛与苯-1,2-二胺的缩合反应，实现了对苯并恶嗪和苯并咪唑的定向合成，产率很高。
