Bromination of isopinocamphone gives 2α,4α-dibromo-10β-pinan-3-one (III) which is rearranged to 3-endo-6-endo-dibromocamphor (IV) when heated with aqueos aceticacid. Analogous rearrangements of 2α-bromo-10β-pinan-3-ones are described.

Chiral 1H-pyrazolo[3,4-b]pyridines fused with nopinane frame were obtained by FeCl3-catalyzed assembling of pinocarvone oxime and 1-aryl-1H-pyrazol-5-amines. Chemical structures of new compounds were solved by NMR spectroscopy and confirmed by quantum chemical calculations and X-ray crystallography.

We report on the design of 1D MOFs based on a nopinane-annelated organic ligand and Co(II) or Ni(II), the variation of which allows tuning the optical modulation bandwidth. Structural and time-resolved analysis revealed the optical modulation mechanism, the rates and its endurance, thereby enriching the list of sustainable MOFs for tunable optical modulators.
