method for the synthesis of substituted pyridines with aldehydes and NH4OAc under mild conditions using air as the oxidant was developed. This oxidative cyclization process involves direct C–H bond functionalization, C–C/C–N bond formation and C–C bond cleavage.
开发了一种无
金属的有效方法,该方法在温和条件下使用空气作为氧化剂合成醛和NH 4 OAc取代的
吡啶。这种氧化环化过程涉及直接的C–H键功能化,C–C / C–N键形成和C–C键裂解。
