Abstract

Some spiro[indoline‐naphthoxazines] I and spiro[indoline‐pyridobenzoxazines] II substituted by different groups were synthesized in order to evaluate their photochromic properties^1^ and to optimize the preparation of spiroheterocyclic systems. In addition, some spiro[indoline‐naphthopyrans] III were also prepared as reference compounds. Their physical and spectroscopic characteristics (UV, ^1^H and ^13^C NMR) were determined. A study using the experimental design methodology allowed to point out the most important factors for improving the reaction yields.
