8-Aminoquinoline (AQ) is a widely used bidentate auxiliary in metal-catalyzed directed C-H functionalization reactions. Herein, we report an efficient and chemoselective method to convert various N-quinolyl carboxamides to primary amides with the treatment of a stoichiometric amount of 2-iodoxybenzoic acid oxidant or the combination of a catalytic amount of 2-iodobenzoic acid and Oxone co-oxidant in mixed solvents of H2O and HFIP. Its unique compatibility with the Phth-protected α-amino acid (αAA) substrates enhances the overall synthetic utility of the AQ-directed palladium-catalyzed C-H functionalization strategy for synthesis of complex αAAs.

Quinoline-based inhibitors of cyclin dependent kinase 2, compositions including the inhibitors, and methods of using the inhibitors and inhibitor compositions are described. The inhibitors and compositions including them are useful for treating disease or disease symptoms. The invention also provides for methods of making CDK-2 inhibitor compounds, methods of inhibiting CDK-2, and methods for treating disease or disease symptoms.

A rapid, one-pot synthesis and mild procedure for the N-phthaloylation of α-amino carboxamides is described. In acetonitrile, these derivatives react with mono-methylphthalate in the presence of BOP and i-Pr2NEt to afford the intermediate Nα-[(o-methoxycarbonyl)benzoyl]amino carboxamides, which undergo rapid cyclization in the presence of aqueous sodium carbonate to afford the corresponding Nα-phthaloylamino carboxamides in excellent yields. The reaction also works efficiently with α-amino esters, α-amino alcohols and dipeptide esters or amides.
