Transition‐Metal‐Free Borylation of Allylic and Propargylic Alcohols
The base‐catalyzed allylic borylation of tertiary allylic alcohols allows the synthesis of 1,1‐disubstituted allyl boronates, in moderate to high yield. The unexpected tandem performance of the Lewis acid–base adduct, [Hbase](+)[MeO‐B(2)pin(2)](−) favored the formation of 1,2,3‐triborylated species...

| Sumario: | The base‐catalyzed allylic borylation of tertiary allylic alcohols allows the synthesis of 1,1‐disubstituted allyl boronates, in moderate to high yield. The unexpected tandem performance of the Lewis acid–base adduct, [Hbase](+)[MeO‐B(2)pin(2)](−) favored the formation of 1,2,3‐triborylated species from the tertiary allylic alcohols and 1‐propargylic cyclohexanol at 90 °C. |
