It's a SnAP! The transformation of aldehydes into N‐unsubstituted 3‐thiomorpholines provides a convenient alternative to metal‐catalyzed cross‐coupling reactions, which are generally unsuited to the functionalization of saturated N‐heterocycles. A copper‐mediated radical cyclization is the key to the mild conditions, high functional group tolerance, and broad substrate scope offered by these reagents
这是SnAP!醛向N-未取代的3-硫代吗啉的转化为金属催化的交叉偶联反应提供了一种方便的替代方法,而金属催化的交叉偶联反应通常不适合饱和N-杂环的功能化。铜介导的自由基环化是这些试剂提供的温和条件,高官能团耐受性和广泛底物范围的关键。
