Syntheses of angular condensed ring systems combining a benzodiazepinic, or benzothiazepinic, and a coumarinic moiety
摘要:
The title compounds were prepared via intermediates resulting from reactions of 3-formyl-4-hydroxycoumarin (1) with omicron-phenylenediamine, omicron-aminophenol, and omicron-aminothiophenol, respectively. Intramolecular ring closures were effected between the free hydroxy and amino or thiol groups.
