The invention relates to oxycarbamoyl compounds of Formula I: The invention is also directed to the use compounds of Formula I to treat, prevent or ameliorate a disorder responsive to the blockadeof calcium channels, and particularly N-type calcium channels. Compounds of the present invention are especially useful for treating pain.
Highly enantioselective catalytic asymmetric epoxidation of α,β-unsaturatedcarboxylic acid imidazolides and simple amides was developed. In the presence of 5–10 mol% of lanthanide–BINOL complexes, the reaction proceeded smoothly with high substrate generality. In particular, in the cases of α,β-unsaturated amides, there was nearly perfect enantioselectivity (>99% ee). The corresponding epoxides were

The disclosure provides compounds of formula II with warheads and their use in treating medical diseases or disorders, such as viral infections. Pharmaceutical compositions and methods of making various compounds with warheads are provided. The compounds are contemplated to inhibit proteases, such as the 3C, CL- or 3CL-like protease. Formula II
Catalytic Asymmetric Epoxidation of α,β-Unsaturated Amides: Efficient Synthesis of β-Aryl α-Hydroxy Amides Using a One-Pot Tandem Catalytic Asymmetric Epoxidation−Pd-Catalyzed Epoxide Opening Process
catalytic asymmetric epoxidation of alpha,beta-unsaturated amides using Sm-BINOL-Ph3As=O complex was succeeded. Using 5-10 mol % of the asymmetric catalyst, a variety of amides were epoxidized efficiently, yielding the corresponding alpha,beta-epoxy amides in up to 99% yield and in more than 99% ee. Moreover, the novel one-pot tandem process, one-pot tandem catalytic asymmetric epoxidation-Pd-catalyzed epoxide
