An efficient electrochemical bromocyclization of allenols has been realized for the synthesis spirocyclic 2,5-dihydrofurans. The reaction used commercially available and nontoxic KBr as brominating source in a simple setup under open-air conditions. Notably, optically active products can be obtained from 2,3-allenols without any racemization, further enhancing synthetic utility.
