The present invention relates to a series of novel compounds, methods to prevent or treat viral infections in animals by using the novel compounds and to said novel compounds for use as a medicine, more preferably for use as a medicine to treat or prevent viral infections, particularly infections with RNA viruses, more particularly infections with viruses belonging to the family of the Flaviviridae, and yet more particularly infections with the Dengue virus. The present invention furthermore relates to pharmaceutical compositions or combination preparations of the novel compounds, to the compositions or preparations for use as a medicine, more preferably for the prevention or treatment of viral infections. The invention also relates to processes for preparation of the compounds.

A rhodium-catalyzed enantioselective formal [4 + 3]-cycloaddition of vinylindoles with vinyldiazoacetates has been developed, affording the dearomative cyclization products containing a newly formedseven-memberedring in up to 99% ee. Rh2(S-DOSP)4 has been proven to be the best catalyst for the cycloaddition of 3-vinylindoles with vinyldiazoacetates, whereas Rh2(S-TCPTTL)4 has enhanced the enantioselectivity
3-Acyl-indole derivative 1 was identified as a novel dengue virus (DENV) inhibitor from a DENV serotype 2 (DENV-2) phenotypic antiviral screen. Extensive SAR studies led to the discovery of new derivatives with improved DENV-2 potency as well as activity in nanomolar to micromolar range against the other DENV serotypes. In addition to the potency, physicochemical properties and metabolic stability
