HETEROCYCLIC ANALOGS OF PLEIADIENE. 72. SULFONES OF PERIMIDINE AND 2,3-DIHYDROPERIMIDINE. SYNTHESIS AND SOME PROPERTIES
Keywords:
perimidine, sulfones, annular prototropAbstract
The arenesulfonation of perimidines has been carried out in polyphosphoric acid and found to occur at the 6(7) and 4(9) positions. Reduction then gave the first representatives of 2,3-dihydroperimidine sulfones. We report a comparative 1H NMR spectroscopic analysis of the arenesulfonyl- and acylperimidines together with their annular prototropic tautomerism.
