efficiency and practicality, good functional group tolerance, and high sustainability, since ambient air and visible light are adequate for the clean conversion of alkenoic acids into their respective lactones. The title method has been used as a case study to elucidate the general mechanistic aspects of the dual selenium-π-acid/photoredox catalysis. On the basis of NMR spectroscopic, mass spectrometric, and
据报道,通过协同的非金属催化剂对促进了链烯酸的好氧脱氢内酯化。标题程序依赖于光氧化还原和硒-π-酸催化剂之间调节的相互作用,这允许以区域控制的方式构造五元和六元内酯环,收率最高可达96%。该方法的显着特征是明显的效率和实用性,良好的官能团耐受性和高度的可持续性,因为环境空气和可见光足以将链烯酸干净地转化为其各自的内酯。标题方法已被用作案例研究,以阐明硒-π-酸/光氧化还原双重催化的一般机理。在NMR光谱,质谱和计算研究的基础上,
