The present invention relates to compounds that are inhibitors of hepatitis B virus (HBV). Compounds of this invention are useful alone or in combination with other agents for treating, ameliorating, preventing or curing HBV infection and related conditions. The present invention also relates to pharmaceutical compositions containing said compounds.
The present invention relates to ethynyl derivatives of formula (I) wherein • R is phenyl, 3-fluorophenyl, 4-fluorophenyl or 2,5-di-fluorophenyl; • or to a pharmaceutically acceptable acid addition salt, in enantiomerically pure form with the absolute configuration as shown in formula (I). It has now surprisingly been found that the compounds of general formula I are allosteric modulators of the metabotropic glutamate receptor subtype 5 (mGluR5) whic are useful for he treatment of schizophrenia, cognitive disorders, fragile X sydrome or autism and which show advantageous biochemical-, physicochemical- and pharmacodynamic- properties compared to compounds of prior art.
