The present invention is directed to novel amino-substituted seven-membered heterocyclic compounds of structural formula (I) which are inhibitors of the dipeptidyl peptidase-IV enzyme and which are useful in the treatment or prevention of diseases in which the dipeptidyl peptidase-IV enzyme is involved, such as diabetes and particularly Type 2 diabetes. The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases in which the dipeptidyl peptidase-IV enzyme is involved.
strong acids and bases. In neutral 60% (v/v) dioxan-deuterium oxide solutions the rate constants of exhange could be evaluated. The logarithm of the pseudo first order rate constants of hydrolysis are linear in H0 for CHLO4, HCI and H2SO4 as the catalysts. The slopes of these linear plots increase with increasing nucleophilicity of the conjugate base of the acid. At constant ionic strength the pseudo first
