The present invention is directed to novel nanomolar and picomolar inhibitors of HIV reverse transcriptase, pharmaceutical compositions therefrom and methods for inhibiting reverse transcriptase and treating HIV infections, especially included drug resistant strains of HIV-1 and HIV-2 and/or secondary disease states and/or conditions which occur as a consequence of HIV infection.

A generalmethod for a highly regioselective copper-catalyzed cross-coupling of two aromatic compounds using iodine as an oxidant has been developed. The reactions involve an initial iodination of one arene followed by arylation of the most acidicC-H bond of the other coupling component. Cross-coupling of electron-rich arenes, electron-poor arenes, and five- and six-membered heterocycles is possible

A highly effective protocol for palladium-catalyzed selective arylation and heteroarylation of indolizines at C-3 has been developed. Mechanistic studies unambiguously support an electrophilic substitution pathway for this transformation.

The controlled mono-addition of indolizines to isatins under very mild conditions is described. The reaction occurs in water using diphenylphosphate as the catalyst, which is dramatically accelerated by surfactant addition. 3-Hydroxy-3-indolizinyl-2-oxindole scaffolds were synthesized in up to >99% yield. Notably, in organic solvents only bis-addition products were observed.

borylation of indolizines has not previously been reported and in this communication, we describe our preliminary efforts to apply this chemistry to this scaffold and contrast this approach to directed metalation. Through these methodologies were possible obtain a library of substituted indolizines functionalized in both pyridinic and pyrrole ring.
