A novel chemical reagent – difluoromethyl nitrile oxide, CF2HCNO – was generated in situ for the first time. The synthesis commenced with ethyl difluoroacetate and included only two chemical steps. The difluoromethyl nitrile oxide smoothly participated in [3+2]-cycloaddition reactions with alkynes and enamines to give CF2H-isoxazoles; these products are promising cores for agrochemistry.

The present invention provides compounds having high affinity for amyloid β-protein which are for the diagnosis of diseases in which amyloid β-protein accumulates, for agents for specifically staining amyloid β-protein, and for the treatment and/or prophylaxis of diseases in which amyloid β-protein accumulates. The present invention also provides probes and staining agents for neurofibrillary tangles.
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.
