Regioselective Synthesis of 4‐Aryl‐1,3‐dihydroxy‐2‐naphthoates through 1,2‐Aryl‐Migrative Ring Rearrangement Reaction and their Photoluminescence Properties

4‐Aryl‐1,3‐dihydroxy‐2‐naphthoates having the less accessible 1,2,3,4‐tetrasubstituted naphthalene scaffold and that show photoluminescence emission from solid state as well as in solutions, were selectively synthesized from brominated lactol silyl ethers through the 1,2‐aryl‐migrative ring rearrangement...
