Synthesis and self association of 4,7-diamino-2,9-dimethyl-5,6,11a-triaza-6,11,11a,12-tetrahydronaphthacene derivatives as dibenzoguanidine receptors for oxoanion recognition
Abstract
Syntheses of 4,7-diamino-2,9-dimethyl-5,6,11a-triaza-6,11,11a,12-tetrahydronaphthacene and of their 2-naphthoyl and butyroyl amide derivatives are described; the U-shaped 2-naphthoyl derivative stabilizes as an interlocked dimer in CDCl3 solution.
