Synthesis and Conformational Analysis of Naphthoxazine-Fused Phenanthrene Derivatives

open access: yesMolecules, 2020
The synthesis of new phenanthr[9,10-e][1,3]oxazines was achieved by the direct coupling of 9-phenanthrol with cyclic imines in the modified aza-Friedel–Crafts reaction followed by the ring closure of the resulting bifunctional aminophenanthrols with ...
