| Popis: |
Some spiro[indoline-naphthoxazines] I and spiro[indoline-pyridobenzoxazines] II substituted by different groups were synthesized in order to evaluate their photochromic properties1 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, 1H and 13C NMR) were determined. A study using the experimental design methodology allowed to point out the most important factors for improving the reaction yields. |
