An efficient synthesis of 2-aryl-4H-pyrano[2,3-b]pyridine-4-ones is reported, using a one-pot, two step process in the presence of pyridinium hydrochloride. The methodology is compatible with a series of functional groups useful for the synthesis of second generation analogs, as part of our SAR program. In addition, the method proved to be scalable (>100 g), allowing for efficient synthesis of material to support animal studies. (C) 2009 Elsevier Ltd. All rights reserved.

The present invention relates to novel tri- and tetrasubstituted pyrones and related structures which potently inhibit the HIV aspartyl protease blocking HIV infectivity. The pyrone derivatives are useful in the development of therapies for the treatment of bacterial and viral infections and diseases, including AIDS. The present invention is also directed to methods of synthesis of multifunctionalized pyrones and of related structures.
