efficient strategy for the oxidative spirocyclization of biaryl ynones has been developed, where nonsubstituted groups were on the para-position of the dearomatized aryl rings. This cascade reaction uses the stable and readily available AgSCF3 as a trifluoromethylthio radical precursor and the reaction occurs smoothly in the presence of K2S2O8 and TBHP via a 6-exo-trig radical cyclization, providing a variety
已经开发了一种直接有效的联芳基炔酮氧化螺环化策略,其中未取代的基团位于脱芳基芳环的对位。该级联反应使用稳定且易于获得的 AgSCF 3作为三氟甲硫基自由基前体,在 K 2 S 2 O 8和 TBHP存在下通过6 - exo -trig 自由基环化反应顺利进行,提供多种 SCF 3 -含有高产率的螺[5,5]三烯酮。
