ylethyl)furan‐2‐yl]methyl}phenol (2), were synthesized starting from 2‐furaldehyde. A Wittig reaction of 2‐furaldehyde with benzyltriphenylphosphonium bromide followed by reduction of the alkene CC bond with Mg gave 2‐(2‐phenylethyl)furan (5). Lithiation of 5 with BuLi at −78° followed by alkylation with benzyl bromide gave natural product 1. In another approach, FriedelCrafts acylation of compound
