Stereoselective functionalisation of pinopyridine with anisidines and o-phenylenediamine
摘要:
Benzylic oxidation of pinopyridine with SeO2 affords the corresponding keto derivative (71% yield) whose reductive amination with o- and p-anisidines proceeds stereoselectively to give 8R-amino derivatives; the reaction with o-phenylenediamine results in achiral pyridophenazine derivative possessing intense blue fluorescence at 441 nm. Structures of o-anisidine derivative and substituted pyridophenazine have been characterized by 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.
