Pertosylated polyaza[n](9,10)anthracenophanes

1997

Abstract Pertosylated polyaza[n](9,10)antracenophanes have been obtained in high yields by a modification of the Richman-Atkins methodology. Molecular Mechanics calculations as well as the crystal structure of the N,N′,N″,N‴-Tetratosyl-2,6,9,13-tetraaza[14](9,10)anthracenophane 4 derivative reveal the existence of a well defined cavity where both the aromatic moiety and the nitrogen donor atoms converge. Reduced mobility of the aliphatic chain is also observed as well as the presence of some strain at the benzylic positions.
