Transannular ring stabilisation by hydrogen bonding in trianthranilide derivatives. X-Ray structures of 5,11-dibenzyl- and 5,11-dimethyltribenzo[b,f,j][1,5,9]triazacyclododecine-6(5H),12(11H),18(17H)-trione(NN′-dibenzyl- and NN′-dimethyl-trianthranilide)

Abstract

Crystal structure determinations of two closely related tribenzo[b,f,j][1,5,9]triazacyclododecine-6(5H),12(11H),18(17H)-trione (trianthranilide) derivatives have confirmed n.m.r. conclusions that both adopt a helical conformation in the solid state; a different transannular hydrogen bond has been found in each of these structures, in one case involving a severely distorted trans-amide group.
