通过假想的中间体α-氧代金卡宾可能被外部亲核试剂(例如苯并[ c ]异恶唑(蒽))捕获,从而中断了导致蒽基的2-炔基硝基苯的Au催化硝基炔环异构化。首先,它提供了具有连续C–O,C–N和N–N键形成的高度官能化的3-酰基-(2-甲酰基苯基)-2 H-吲唑的简单合成方法。这为在α-催化的炔炔的内部氧化还原过程中α-氧羰金的存在提供了间接支持。

The known nitrogen-transfer reagent 1,2-benzo[d]isoxazole has been used to trap the postulated α-oxo gold carbene intermediate involved in the [Au]-catalyzed internal redox process of 2-alkynylnitrobenzenes. This process led us to develop a general convergent method for the synthesis of highlyfunctionalized quinazoline 1-oxides.

interrupted by possible trapping of the postulated intermediate α-oxo gold carbene with an external nucleophile such as benzo[c]isoxazole (anthranil). At the outset, this provides a simple synthesis of highly functionalized 3-acyl-(2-formylphenyl)-2H-indazoles with the sequential C–O, C–N, and N–N bond formations. This provides indirect support for the existence of α-oxo gold carbenes in the [Au]-catalyzed internal
