Picornaviral 3C protease inhibitors, obtainable by chemical synthesis, inhibit or block the biological activity of the picornaviral 3C protease. These compounds, as well as pharmaceutical compositions that contain these compounds, are suitable for treating patients or hosts infected with one or more picornaviruses.
pungent principle of hot pepper, and its 15 analogs have been efficiently synthesized. The key step of this synthetic sheme is the orthoester Claisen rearrangement, which transformed allylic alcohols 2A-C to (E)-alkenoates 3A-C () in a highly stereoselective manner. The subsequent carbon chain elongations on 3 based on the cyanation or the malonic acid estersynthesis afforded (E)-alkenoic acids 8, which
