HIVintegraseinhibitors based on a novel bicyclic pyrimidinonecore is presented. Nine variations of the core scaffold are evaluated leading to optimization of the 6:6 core giving compound 48 with an EC50 of 3 nM against wild type HIV infected T-cells.
The present invention provides a compound of Formula (I) or a salt thereof;
and therapeutic uses of these compounds. The present invention further provides pharmaceutical compositions comprising these compounds, and compositions comprising these compounds with a therapeutic co-agent.

A simple approach toward N-3-substituted-2,3-diaminopyridines is presented, based on Pd-catalyzed C,N-cross coupling. The use of RuPhos- and BrettPhos-precatalysts in combination with LiHMDS allows for C,N-cross coupling reactions of unprotected 3-halo-2-aminopyridines with primary and secondary amines.
