A novel approach to 2,5-disubstituted 1,3,4-oxadiazoles derivatives via a decarboxylative cyclization reaction by photoredox catalysis between commercially available α-oxocarboxylic acids and hypervalent iodine(III) reagent is described. This powerful transformation involves the coupling reaction between two different kinds of radical species and the formation of C–N and C–O bonds.
描述了一种新颖的方法,该方法通过可商购的α-氧代羧酸和高价碘(III)试剂之间的光氧化还原催化脱氧环化反应来进行2,5-二取代的1,3,4-恶二唑衍生物。这种有力的转变涉及两种不同种类的自由基之间的偶联反应以及C–N和C–O键的形成。
