The first diastereoselectiveallylation reaction at the α-position of ketones by using tert-butanesulfinamide as a chiral auxiliary is explored. Excellent yields and high diastereomeric ratios were achieved under palladium catalysis in the presence of a readily available achiral phosphine ligand. The chiral auxiliary was removed in quantitative yield under the optimized conditions without any racemization

We describe the design, synthesis, and biological evaluation of a series of novel HIV-1proteaseinhibitors with carboxamide derivatives as the P2 ligands. We have specifically designed aminothiochromane and aminotetrahydronaphthalene-based carboxamide ligands to promote hydrogen bonding and van der Waals interactions in the active site of HIV-1protease. Inhibitors 4e and 4j have shown potent enzyme
