1-Amino-2-vinylcyclopropanecarboxylic acid ester, which is useful as a synthetic intermediate of pharmaceuticals, can be produced by a process of producing 1-amino-2-vinylcyclopropanecarboxylic acid ester represented by formula (4):
including a step of hydrolysis of an optically active 1-N-(arylmethylene)amino-2-vinylcyclopropanecarboxylic acid ester represented by formula (3):
which is obtained by reacting an N-(arylmethylene)glycine ester represented by formula (1):
with a compound represented by formula (2):
in the presence of a base and an optically active quaternary ammonium salt.
Hepatitis C virus inhibitors having the general formula
are disclosed. Compositions comprising the compounds and methods for using the compounds to inhibit HCV are also disclosed.
