Synthesis of novel photochromic 6-benzyloxo-spirobenzopyran compounds

The synthesis of four novel derivatives of 1′,3′,3′- trimethylspiro-[2H-1]-benzopyran-6-benzyloxo-2,2′-indoline is reported. The synthetic approach to these compounds involves the preparation of the key compound, 3-formyl-4-hydroxybenzophenone, by means o
