The syntheses of some methoxy-substituted bicyclic lactams, of the types 3 and 4, are reported employing two different conditions for the Schmidt reaction of appropriate ketones and employing two different conditions for the Beckmann rearrangement of the corresponding ketoximes. The alkyl to aryl migration ratios of the reactions were determined by high-performance liquid chromatography analysis of

The present invention is directed to novel fused triazole derivatives which are inhibitors of the dipeptidyl peptidase-IV enzyme (“DPP-IV inhibitors”) 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.
