Synthesis and spectrophotometric analysis of 1-azafluorenone derivatives
A new extension for the 'one pot' construction of diverse 1-azafluorene derivatives featuring a Diels-Alder/retro-Diels-Alder cycloaddition is reported. Conditions were also determined for oxidation to the derived azafluorenones. The spectrophotometric analysis of five different azafluorenones were performed. Moderate fluorescence was observed with azafluorenone derivatives that bear an imbedded pyridone motif; whereas those bearing substituted pyridines do not fluoresce.

Etude de la stereochimie de la reaction de cycloaddition dipolaire-1,3 de quelques 5-phenyl-3,6-dihydro-2H-1,4-oxazin-2-ones avec les N-methyl et N-phenylmaleimides
Six derivatives of 5-phenyl-3,4-dihydro-2H-1,4-oxazin-2-ones 1 were synthetized from α-amino acids.These compounds are precursors of six-membered cyclic azomethine ylids involving one stereocenter.The 1,3-dipolar species react with N-methyl and N-phenylma
