There is disclosed pyridine- and pyrimidinecarboxamide compounds useful as pharmaceutical agents, synthesis processes, and pharmaceutical compositions which include pyridine- and pyrimidinecarboxamides compounds. More specifically, there is disclosed a genus of CXCR2 inhibitor compounds that are useful for treating a variety of inflammatory and neoplastic disorders.
Disclosed is a novel class of compounds of formula (I)
wherein V, A, Y, Z, R1, E, X and D are as defined in the specification. These compounds act to antagonize the action of the glucagon hormone on the glucagon receptor. Owing to their antagonizing effect of the glucagon receptor, the compounds are suitable for treating or preventing glucagon-mediated conditions and diseases such as hyperglycemia, Type 1 diabetes, Type 2 diabetes and obesity.
Herein we report a novel palladium-catalyzedoxidativecarbonylation reaction for the synthesis of phthalimides with high atom- and step-economy. In our strategy, the imine and H2O, which are generated in situ from the condensation of aldehyde and amine, serve as self-sufficient directing group and nucleophile, respectively. This method provides rapid access to phthalimides starting from readily available

by different synthetic routes: (i) phenylazo derivatives; (ii) naphthalimide azo derivatives; and (iii) phthalimide azo derivatives. Model compounds in each system were synthesized for spectroscopic comparison. Confirmation of structure was achieved using a combination of NMR and IR spectroscopy to ascertain the functional sites (i.e., the azo and the cyclicimides), while mass spectrometry and UVvis
