AbstractThe 1,9,17-triaza[2.2.2]metacyclophane-2, 10, 18-trione derivatives (1) - (3) have been synthesised. X-Ray crystallography shows that the 1,9,17-trimethyl derivative (3) adopts a Crown conformation (11) in the solid state. Dynamic n.m.r. spectroscopy indicates that both the 1,9-dimethyl-17-benzyl- (2) and 1,9,17-trimethyl- (3) derivatives exist as interconverting mixtures of Crown (11) and Saddle (12) conformations with the former predominating at equilibrium in solution. © 1980.
