Softly does it: The title reaction, catalyzed by a AgPF6/(R)‐biphep‐type ligand/DBU complex, is described (see scheme). This protocol gives efficient access to syn‐configured α‐sulfanyl‐β‐hydroxy lactones in a highly enantioselective manner. In one particular case, the sulfide group was stereospecifically replaced with a hydroxy group to afford an enantioenriched tertiary alcohol, which upon further

A method whereby a compound having HCV replication inhibitory activity and desired optical activity can be synthesized selectively and at high yield in a small number of steps by using a compound having a specific chiral auxiliary as a starting compound is provided.
A compound represented by the formula (1-8):
[wherein Y represents a group represented by the following formula:
Q represents a protected carbonyl group; D represents -(CH2)m-R', etc.; and n represents an integer of 0 to 10].
The object of the present invention is to provide a pharmaceutical composition for preventing or treating viral infectious diseases. The compounds of the present invention have extremely potent anti-HCV activity and HCV growth inhibitory effects, and since they also only demonstrate mild cytotoxicity in vivo, a pharmaceutical composition containing the compound of the present invention is extremely useful as an anti-HCV preventive/therapeutic agent.
