2-(4-Chloro-phen-yl)-5-(3,4-dimethoxy-pheneth-yl)-6,7-dihydro-pyrazolo[1,5-a]pyrazin-4(5H)-one.

ABSTRACT: In the title compound, C(22)H(22)ClN(3)O(3), the dihedral angles between the planes of the benzene rings and the pyrazole ring are 16.05?(10) and 84.84?(10)°. The conformation of the six-membered heterocyclic ring is close to a screw-boat. The crystal packing is stabilized by weak inter-molecular C-H?O inter-actions and is also consolidated by C-H?? inter-actions.

2-(3-Chloro-4-hydroxy-phen-yl)-N-(3,4-dimethoxy-pheneth-yl)acetamide.

Project description:The title compound, C(18)H(20)ClNO(4), was synthesized during the generation of a combinatorial library based on the fungal natural product 3-chloro-4-hydroxy-phenyl-acetamide. It crystallizes as discrete mol-ecules linked by inter-molecular C(9) chains of N-H⋯O and O-H⋯O hydrogen bonds which in turn combine to form chains of R(2) (2)(20) rings.

Project description:In the title compound, C(14)H(10)N(2)O(2), the dihedral angle between the heterocyclic ring system and the phenyl ring is 45.8 (5)°. Weak inter-molecular C-H⋯N hydrogen bonding is present in the crystal structure.

2-Methyl-1,10b-dihydro-5H-pyrazolo[1,5-c][1,3]benzoxazin-5-one.

Project description:In the title compound, C(11)H(10)N(2)O(2), a potential inhibitor of the cyclo-oxygenase-2 isoenzyme, the pyrazoline ring exists in a flat-envelope conformation while the puckering of the central oxazine ring is more severe. As a result, the mol-ecule as a whole is non-planar. The formal sp(3) pyrazoline N atom is sp(2) hybridized, with the lone-pair electrons delocalized through conjugation with the carbonyl group rather than the double bond of the pyrazoline ring.

4,4-Dimethyl-3,4-dihydro-pyrido[2',3':3,4]pyrazolo-[1,5-a][1,3,5]triazin-2-amine ethanol monosolvate.

Project description:In the title compound, C(10)H(12)N(6)·C(2)H(5)OH, the planarity of the heterocyclic system is slightly distorted at the triazine ring (r.m.s. deviation = 0.1191?Å), which adopts a conformation best described as inter-mediate between a flattened twisted boat and a half-boat with the tertiary Csp(3) atom at the bow. In the crystal, mol-ecules form centrosymmetric dimers connected by N?H-O and O?H-N hydrogen bonds between the amino group H atom, the ethanol solvent mol-ecule and the triazine N atom, making an R(4) (4)(12) graph-set motif. The other H atom of the amino group and the H atom on the endocyclic N atom form N?H-N hydrogen bonds with the N atoms of the pyrazole and pyridine rings, respectively, linking the mol-ecules into C(7)C(7) chains with the R(2) (2)(8) binary graph-set motif running along [010].

Project description:In the title compound, C(11)H(9)N(5)O, the pyrazolo-pyrimidin-4-one ring system is almost planar, with a maximum deviation of 0.0546?(13)?Å for the O atom.
