The stepwise synthesis of N,N′,N″-trimethyltetra-anthranilide (13) is reported and the temperature dependence of the 1Hn.m.r. spectrum of N-benzyl-N′,N″,N‴-trimethyltetra-anthranilide (15) is interpreted in terms of equilibration between three diastereoisomeric conformations in solution. Although there is 1Hn.m.r. spectral evidence for the presence in solution at room temperature of at least six
