A range of heterocycles, namely thiazoles, imidazoles, imidazopyridines, thiazolidines and dimethoxyindoles, have been synthesised directly from alkenesvia a two-step ketoidoination/cyclisation protocol. The alkene starting materials are themselves readily accessible using many different and well-established approaches, and allow access to a variety of heterocycles with excellent yields and regioselectivity.
The present invention relates to a series of novel imidazo[1,2-α]pyrrolo[3,2-c]pyridines (or also named 6H-1,3a,6-Tri-aza-αy-indacenes) and derivatives thereof, according to formula: (I); The present invention also relates to processes for the preparation of imidazo[1,2-α]pyrrolo[3,2-c]pyridines, their use as. a, medicine, their use to treat or prevent viral infections and their use to manufacture a medicine to treat or prevent viral infections, particularly infections with viruses belonging to the family of the Flaviviridae and more preferably infections with Bovine Viral Diarrhea virus (BVDV).

The present invention relates to compounds of general formula (I) wherein R1 is lower alkyl or lower alkyl substituted by halogen; R2, R3 are hydrogen or tritium; or to a pharmaceutically acceptable acid addition salt. The compounds may be used for binding and imaging tau aggregates and related beta-sheet aggregates including besides others beta-amyloid aggregates or alpha-synuclein aggregates.
