Epoxides as alkylating reagents are unprecedentedly applied in Pd(II)-catalyzed C–H alkylation and oxidative annulation of substituted benzamides to synthesize isoquinolones rather than isochromans, which is accomplished through alerting the previously reported reaction mechanism by the addition of oxidant and TEA. Under these conditions, various isoquinolones have been prepared with yields up to 92%
The first total synthesis of cassiarin A, an antiplasmodial alkaloid isolated from Cassia siamea, was achieved via sequential alkynylation of arenes with Sonogashira coupling and 6- endo-dig-cyclization of phenolic oxygens to the resulting alkynes.
