general Rh(III)-catalyzed synthesis of naphthyridinone derivatives is described. It relies on a double-activation and directing approach leveraging nicotinamide N-oxides as substrates. In general, high yields and selectivities can be achieved using low catalyst loadings and mild conditions (roomtemperature) in the couplings with alkynes, while alkenes require slightly more elevated temperatures.
描述了一般的 Rh(III) 催化合成萘啶酮衍生物。它依赖于利用烟酰胺 N 氧化物作为底物的双重激活和导向方法。通常,在与炔烃的偶联中使用低催化剂负载量和温和条件(室温)可以实现高产率和选择性,而烯烃需要稍微升高的温度。
