The photolysis of substituted o-divinylbenzenes promotes a one-step and metal-free conversion to oxatricycles at room temperature. Irradiation o-divinylbenzenes results in an pericyclic reaction to form cyclic o-quinodiemthane intermediates, which subsequently undergo intramolecular oxa-[4+2] cycloaddition to form oxacyclic derivatives.
在室温下,取代的邻二乙烯基苯的光解促进了一步和无金属的转化为氧三环。辐照邻二乙烯基苯导致周环反应,形成环状邻喹二乙烷中间体,随后中间体进行分子内的oxa- [4 + 2]环加成反应形成oxacyclic衍生物。
