Paragraph 0215, (2013/04/25)
Disclosed is a compound of formula I, a stereoisomer thereof, a cis-trans-isomer thereof, a tautomer thereof, or a mixture thereof, or a pharmaceutically acceptable salt thereof, a solvate thereof or a prodrug thereof, wherein R1, R2, R3 and R4 are each as defined in the present application.

An efficient synthetic methodology to provide indole, 2,3-dihydro-indole, and 3,4-dihydro-2H-quinoline-1-carbothioic acid amide derivatives is described. These conformationally restricted heterobicyclic scaffolds were evaluated as a novel class of HCV inhibitors. Introduction of an acyl group at the NH2 of the thiourea moiety has been found to enhance inhibitory activity. The chain length and the position of the alkyl group on the indoline aromatic ring markedly influenced anti-HCV activity. The indoline scaffold was more potent than the corresponding indole and tetrahydroquinoline scaffolds and analogue 31 displayed excellent activity (EC50 = 510 nM) against HCV without significant cytotoxicity (CC50 >50 μM).

Here, we report a highly effective and chemoselective method of preparing substituted indoles from (E)-2-nitropyrrolidinostyrenes via hydrogenation in the presence of a rhodium catalyst doped by additives such as Ni(NO 3)2·6H2O, Fe(OAc)2 or Co(acac)3. These hydrogenation conditions may also be applied to other substrates. Aromatic nitro compounds and olefins can be selectively reduced in the presence of aromatic benzyl ethers, aromatic halides and aromatic aldehydes.
