synthesis of a novel series of proteaseinhibitors incorporating conformationally constrained cyclicligands for the S2-substrate binding site of HIV-1protease is described. We recently reported urethanes of 3-tetrahydrofuranyl as P2ligands for HIV-1proteaseinhibitors. Subsequently, we have found that the urethane of 3(S)-hydroxysulfolane further increased the in vitro potency of these inhibitors. Furthermore

An enantioselective synthesis of the halogenated medium-ring ether natural product (+)-obtusenyne is reported which uses the ring expansion of a seven-membered ketene acetal by means of a Claisen rearrangement to construct the core nine-membered oxygen heterocycle. The trans substituents across the ether linkage were established by using a transition-metal-catalyzed intramolecular hydrosilation reaction
