A novel direct synthesis of 1,3-dioxo-substituted allenes was developed by copper(I)-catalyzed coupling of α-oxo-alkynes and α-oxo-diazos. It was a sequence of adding substrates-controlled method and the desired products were synthesized chemoselectively by adding α-oxo-alkyne terminally.

通过铜(I)催化α-氧代炔烃和α-氧代重氮的偶联反应,通过控制底物的添加顺序来合成1,3-二氧代取代的烯

通过铜(I)催化α-氧代炔烃和α-氧代重氮偶合的偶联反应,开发了一种新的直接合成1,3-二氧代取代的丙二烯的方法。这是添加底物控制方法的顺序,并且通过末端添加α-氧代炔烃来化学选择性地合成所需的产物。
