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 reaction.
