Radical α-C−H Hydroxyalkylation of Ethers and Acetal
摘要:
Ethers and an acetal were found to undergo direct intermolecular addition to aldehydes under the Et3B/air conditions. This study presents a very unique and simple means for the radical alpha-C-H hydroxyalkylation of oxygen-containing compounds.

report the selective, non‐directed and cross‐dehydrogenative coupling of allylicC(sp3)−Hbonds with C(sp2)−Hbonds of (hetero)arenes. The methodology employs olefins and (hetero)arenes which are abundantly available chemical feedstocks, and could be applied in late‐stage functionalization reactions of pharmaceuticals. Furthermore, the system exclusively delivers the allylic C−C coupling products highlighting
