View Patent ↗The present invention relates to difluoroethyl-oxazole substituted bridged spiro[2.4] heptane derivatives of formula (I), wherein the substituents at the piperidine ring are in trans-arrangement, their preparation and their use as pharmaceutically active compounds.
1. A compound of formula (I)
wherein the substituents at the piperidine ring are in trans-arrangement;
or a salt of the compound.
2. The compound of claim 1 , wherein the compound has a formula (I ST1 ),
wherein the substituents at the piperidine ring are in trans-arrangement;
or a salt of the compound.
3. The compound of claim 1 , wherein the compound is (1S,2R,3R,4R)—N 2 —((4-(1,1-difluoroethyl)oxazol-2-yl)methyl)—N 3 —((3S,4S)-3-fluoropiperidin-4-yl)spiro[bicyclo[2.2.1]heptane-7,1′-cyclopropane]-2,3-dicarboxamide;
or a salt of the compound.
4. The compound of claim 1 , wherein the compound is (1S,2R,3R,4R)—N 2 —((4-(1,1-difluoroethyl)oxazol-2-yl)methyl)—N 3 —((3R,4R)-3-fluoropiperidin-4-yl)spiro [bicyclo [2.2.1]heptane-7,1′-cyclopropane]-2,3 -dicarboxamide; or a salt of the compound.
