Two variants of a new pathway for the synthesis of (±)‐curcumene ether are described. The key steps in these procedures are intramolecular cyclizations of 6‐methyl‐2‐(4‐methylphenyl)hept‐6‐en‐2‐ol and 2‐methyl‐6‐(4‐methylphenyl)hept‐6‐en‐2‐ol by means of an electrochemically generated phenylselenyl cation. This synthetic approach provides significantly better yields than the previously reported protocols
