motif found in many polyphenolic natural products, as well as synthetically useful compounds such as the chiral ligands binol, vapol, and vanol. The new route consists of a radical‐based reaction of an acetal‐tethered biphenyl ether substrate and subsequent hydrolytic cleavage of the dibenzo‐1,3‐dioxepine intermediate.
