Tert-butyl 3-oxo-2,3,4,5,6,7-hexa-hydro-1H-pyrazolo[4,3-c]pyridine-5-carboxyl-ate.

Project description:In the title compound, C(11)H(17)N(3)O(3), the pyrazole ring is approximately planar, with a maximum deviation of 0.005?(2)?Å, and forms a dihedral angle of 5.69?(13)° with the plane through the six atoms of the piperidine ring. In the crystal, pairs of inter-molecular N-H?O hydrogen bonds form dimers with neighbouring mol-ecules, generating R(2) (2)(8) ring motifs. These dimers are further linked into two-dimensional arrays parallel to the bc plane by inter-molecular N-H?O and C-H?O hydrogen bonds.

Project description:The title compound, C(29)H(17)FN(4)O(2), may be used as a new precursor for obtaining bioactive mol-ecules. There are two crystallographically independent mol-ecules in the asymmetric unit.

Project description:There are two crystallographically independent mol-ecules in the asymmetric unit of the title compound, C(26)H(17)FN(4)O(3), which differ in the dihedral angles between the aromatic rings (fluorophenyl, phenyl) and the pyrrolopyrimidine rings [0.6?(3)/76.3° and 73.7?(3)/64.6°, respectively].
