Abstract
A synthetic access to photochromic spirooxazines is developed through the condensation of methylene-substituted azaheterocycles on 1-amino-2 -naphthols in presence of an oxidizing agent. Compared to usual prepar ation of this kind of compounds (via 1-nitroso-2-naphthols), yields ar e generally good and approaches to Further spiroheterocyclic oxazines are possible.
