Formula (I). The description discloses the preparation of exemplary compounds (e.g. pages 113 to 354 examples 1 to 221) as well as pharmacological studies with relevant data (e.g. pages 355 to 367; examples A to E; tables 1 to 5). Exemplary compounds are e.g. 2-{6-[(1,3-benzothiazol-2-yl) amino]-1,2,3,4-tetrahydroquinolin-1-yl}-1,3-thiazole-4-carboxylic acid (example 1) or e.g. 3-{1-[(adamantan-1-yl)methyl]-5- methyl-1H-pyrazol-4-yl}-6-{3-[(1,3-benzothiazol-2-yl)amino]-4- methyl-5H,6H,7H,8H-pyrido[2,3-c]pyridazin-8-yl]pyridine-2-carboxylic acid (example 24).

We present a new approach to disubstituted diamondoids from corresponding carboxylic acids. A dirhodium-acetate-catalyzed (1 mol-%) nitrene insertion reaction of sulfamides was, for the first time, applied to intramolecular C-H functionalization reactions of rigid tricyclic frameworks. This straightforward approach enables the effective and regioselective synthesis of a variety of diamondoid-based cyclic sulfamidates, which are synthetically valuable building blocks. Reductive deprotection of the sulfamidate moiety leads to corresponding 1,3-amino alcohol derivatives. Oxidation of the sulfamidate moiety by KMnO4 provides access to 1,3-keto alcohols or imines. Finally, we report the synthesis of Vildagliptin analogues as new antidiabetic drug candidates (DPP-4 inhibitors). Intramolecular dirhodium-acetate-catalyzed (1 mol-%) nitrene insertion reactions provide direct access to 1,2-disubstituted diamondoids. This approach was applied to the synthesis of Vildagliptin (DPP-4 inhibitor) analogues.

The discovery of new Bcl-2 protein-protein interaction antagonists is described. We replaced the northern fragment of ABT737 (π-π stacking interactions) with structurally simplified hydrophobic cage structures with much reduced conformational flexibility and rotational freedom. The binding mode of the compounds was elucidated by X-ray crystallography, and the compounds showed excellent oral bioavailability and clearance in rat PK studies.
