control the stereochemistry of sensitized photooxygenation of alkenes via singlet oxygen (ene reaction) are selectively reported. We also introduce our most recent stereoelectronic effects on the singlet oxygen–ene reaction. The origin of site selectivity and solvent-dependent stereoselectivity in this classical ene reaction with simple as well as functionalized alkenes is highlighted. These studies
有选择地报道了控制经由单线态氧(烯烃反应)的烯烃的敏化光氧化的立体化学的因素。我们还介绍了我们对单线态氧-烯反应的最新立体电子效应。在这种经典的烯键反应中,无论是简单的还是官能化的烯烃,其位点选择性和溶剂依赖性立体选择性的起源都得到了强调。这些研究和其他类似研究大大提高了单线态氧在天然和非天然产物合成中的效用。
