reverse transcriptase, a protease, and an integrase. The latter is responsible for the integration of the viral genome into the human genome and, therefore, represents an attractive target for chemotherapeutic intervention against AIDS. A drug based on this mechanism has not yet been approved. Benzyl-dihydroxypyrimidine-carboxamides were discovered in our laboratories as a novel and metabolically stable
secondary, and tertiary alkyl nitriles and thiocyanates are easily synthesized. Moreover, an asymmetric decarboxylative cyanation by applying a chiralCu catalyst is also developed to afford chiral nitriles in high enantioselectivity. The mechanistic details and the origin of the high enantioselectivity are further investigated by the mechanistic experiments and the density functional theory calculations.

In the context of HIV-integrase, dihydroxypyrimidine and N-methyl pyrimidone inhibitors the cellular activity of this class of compounds has been optimized by the introduction of a simple methyl substituent in the alpha-position of the C-2 side chains. Enhanced passive membrane permeability has been identified as the key factor driving the observed cell-based activity improvement. The rat PK profile of the alpha-methyl derivative 26a was also improved over its des-methyl exact analog. (C) 2009 Elsevier Ltd. All rights reserved.
