The present invention relates to a process for producing amino acid derivatives such as optically active β-amino acid in short steps with good yield and high optical purity, which comprises reacting a keto acid of the formula (1):
wherein R
1
is hydrogen, an optionally substituted hydrocarbon, etc.; R
2
is a spacer; and R
3
is an optionally substituted alkoxy, etc., or a salt thereof, with ammonia or an amine or a salt thereof in the presence of a chiral catalyst and in the presence or absence of an acid and/or a fluorine-containing alcohol, to give an amino acid derivative of the formula (2):
wherein Q is a group formed by removing one hydrogen atom from ammonia or an amine; X′ is an acid and/or a fluorine-containing alcohol; and b is 0 or 1.
Disclosed herein are compounds useful for treating a viral infection, such as HCV.

Design and structure–activity relationships of potent and selective inhibitors of undecaprenyl pyrophosphate synthase (UPPS): Tetramic, tetronic acids and dihydropyridin-2-ones
Based on a pharmacophore hypothesis substituted tetramic and tetronic acid 3-carboxamides as well as dihydropyridin-2-one- 3-carboxamides were investigated as inhibitors of undecaprenyl pyrophosphate synthase (UPPS) for use as novel antimicrobial agents. Synthesis and structure - activity relationship patterns for this class of compounds are discussed. Selectivity data and antibacterial activities for selected compounds are provided.
