coumarin derivatives via a tandem double bond isomerization/oxidative cyclization of cinnamic acids. Inexpensive and stable xanthone was used as the photocatalyst, and readily available Selectfluor was used as the oxidant. This method tolerates a wide range of functional groups and offers excellent chemical yields in general. Besides, the photocatalytic oxidative cyclization of cinnamic acid esters gives
我们已经通过肉桂酸的串联双键异构化/氧化环化开发了一种香豆素衍生物的有效光催化合成方法。廉价,稳定的x吨酮用作光催化剂,易购的Selectfluor用作氧化剂。该方法可耐受各种官能团,并且通常可提供出色的化学收率。此外,肉桂酸酯的光催化氧化环化得到二聚的木脂素型产物。
