The 4-hydroxy-5,6-dihydropyrone template was utilized as a flexible scaffolding from which to build potent active site inhibitors of HIVprotease. Dihydropyrone 1c (5,6-dihydro-4-hydroxy-6-phenyl-3-[(2-phenylethyl)thio]-2H-pyran-2-one) was modeled in the active site of HIVprotease utilizing a similar binding mode found for the previously reported 4-hydroxybenzopyran-2-ones. Our model led us to pursue

A practical synthesis of perfluoroalkyl sulfides is described. The method employs stable and readily accessible thiosulfonates as new electrophiles with commercial nucleophilic perfluoroalkylating reagents. The mild reaction conditions allow access to a wide variety of both aryl- and alkyl-substituted perfluoroalkyl sulfides amenable to pharmaceutical development. Furthermore, the reaction operation
A mild and odorless copper-catalyzed thiolation of terminal alkynes with thiosulfonates is described. The broad substrate scope provides convenient access to a wide variety of sulfur-containing heterocycles. In particular, divergent benzoheteroles are efficiently prepared in a simple manner by thiolation of ethynylbenzenes bearing ortho-nucleophilic functional groups followed by iodocyclization.
