Various benzyl ethers were converted to benzyl arenes via a FeCl3-catalyzed Friedel–Crafts alkylation reaction under mild condition in good yields. This method also offered a simple and practical approach to synthesize di- or tri-aryl methanes and aryl heteroaryl methanes through the activation of C–O bonds.
of a methoxy group on an aromatic ring allows this group to be used as a traceless activating and directing group for aromatic functionalization reactions. Although several catalytic methods for the reductive cleavage of anisole derivatives have been reported, all are applicable only to π-extended aryl ethers, such as naphthyl and biphenyl ethers, while monocyclic aryl ethers cannot be reduced.

The present invention relates to a fused ring compound represented by the following formula [I]
wherein each symbol is as defined in the specification, or a pharmaceutically acceptable a salt thereof, and a hepatitis C virus (HCV) polymerase inhibitor and a therapeutic agent for hepatitis C containing this compound. The compound of the present invention shows an anti-HCV activity based on the HCV polymerase inhibitory activity, and useful as an agent for the prophylaxis or treatment of hepatitis C.
A process for producing an aromatic aldehyde compound represented by a general formula (3):
(wherein R′ and n are as defined below), which comprises reacting a benzyl compound represented by a general formula (1):
(wherein R may represents hydrogen atom, n represents an integer of 1 to 6, and R′ may be the same or different and represent a hydrogen atom or an alkyl gorup, an alkyl group or a phenyl group which may have a substituent) with an oxy-compound of bromine represented by the formula (2):
MBrO
m
(2)
(wherein M represents a hydrogen atom or a metal atom, and m represents an integer of 1 to 3) in the presence of an acid catalyst. According to this method, an aromatic aldehyde compound can be produced in high selectivity by a simple operation without using an expensive catalyst or transition metal.
