| Abstract | The stepwise synthesis of 1,9-dimethyl-1,9,17-triaza[2.2.2]metacyclophane-2,10,18-trione (1) from methyl m- aminobenzoate and m-nitrobenzoyl chloride is reported. The temperature dependences (i) of the1H-decoupledl3C n.m.r. spectrum of the 1,9,17-trimethyl derivative (2) and (ii) of the1H n.m.r. spectrum of the 1,9-dimethyl-17- benzyl derivative (3) are interpreted in terms of equilibration between diastereoisomeric crown and saddle conformations in solution. The 1,9-dimethyl derivative (1) is believed to exist predominantly in the saddle conformation in solution. © Royal Society of Chemistry. |
