3,28-Diacet-oxy-29-bromo-betulin.

ABSTRACT: In the title mol-ecule, C(34)H(53)BrO(4), all the cyclo-hexane rings adopt chair conformations, while the cyclo-pentane ring adopts an envelope conformation. In the crystal, weak inter-molecular C-H?O hydrogen bonds link the mol-ecules into corrugated sheets parallel to the ab plane.

Comparison of the crystal structures of methyl 4-bromo-2-(meth-oxy-meth-oxy)benzoate and 4-bromo-3-(meth-oxy-meth-oxy)benzoic acid.

Project description:The title compounds, C10H11BrO4, (I), and C9H9BrO4, (II), are derivatives of bromo-hy-droxy-benzoic acids. Compound (II) crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. In both (I) and (II), the O-CH2-O-CH3 side chain is not in its fully extended conformation; the O-C-O-C torsion angle is 67.3?(3) ° in (I), and -65.8?(3) and -74.1?(3)° in mol-ecules A and B, respectively, in compound (II). In the crystal of (I), mol-ecules are linked by C-H?O hydrogen bonds, forming C(5) chains along [010]. The chains are linked by short Br?O contacts [3.047?(2)?Å], forming sheets parallel to the bc plane. The sheets are linked via C-H?? inter-actions, forming a three-dimensional architecture. In the crystal of (II), mol-ecules A and B are linked to form R 2 (2)(8) dimers via two strong O-H?O hydrogen bonds. These dimers are linked into ?A-B?A-B?A-B? [C 2 (2)(15)] chains along [011] by C-H?O hydrogen bonds. The chains are linked by slipped parallel ?-? inter-actions [inter-centroid distances = 3.6787?(18) and 3.8431?(17)?Å], leading to the formation of slabs parallel to the bc plane.

2-(4-Bromo-phen-oxy)propanohydrazide.

Project description:The title compound, C(9)H(11)BrN(2)O(2), is an important inter-mediate for the synthesis of heterocyclic compounds such as azoles, 2,5-disubstituted-1,3,4-oxadiazo-les and 5-substituted 2-mercapto-1,3,4-oxadiazo-les. The bromo-phen-oxy group subtends a dihedral angle of 82.81?(7)° with the plane passing through the propanohydrazide moiety. The crystal structure is stabilized by inter-molecular N-H?O hydrogen bonds that form columns extending along the b axis.

1-Bromo-2-(10?-dihydro-artemisin-oxy)ethane.

Project description:The title compound, C(17)H(27)BrO(5), DEB, is a derivative of artemisinin which is used in malara therapy. The OR-group at C12 is cis to the CH(3)-group at C11 and axially oriented on ring D which has a chair conformation. The crystal packing is stabilized by several weak inter-molecular C-H?O inter-actions, which combine to form a C-H-O bonded network parallel to (001).

Bis(2-bromo-5-methyl-phen-oxy)methane.

Project description:The complete mol-ecule of the title compund, C(15)H(14)Br(2)O(2), is generated by the application of crystallographic twofold symmetry, with the central C atom lying on the rotation axis. The dihedral angle between the benzene rings is 62.4 (3)°. In the crystal, short Br⋯Br contacts [3.4885 (16) Å] occur.

Methyl 2,6-bis-[(5-bromo-4,6-dimeth-oxy-pyrimidin-2-yl)-oxy]benzoate.

Project description:In the title compound, C(20)H(18)Br(2)N(4)O(8), the inter-planar angle of the pyrimidine rings is 75.1 (2)°. The central benzene ring is inclined at inter-planar angles of 66.5 (2) and 71.9 (2)° with respect to the two pyrimidine rings. In the crystal structure, adjacent mol-ecules are connected into two-mol-ecule-thick arrays parallel to the bc plane via short Br⋯Br [3.5328 (12) Å] and Br⋯O [3.206 (3) and 3.301 (4) Å] inter-actions. A weak inter-molecular π-π aromatic stacking inter-action [centroid-centroid distance = 3.526 (3) Å] is also observed.

Project description:In the title compound, C(12)H(10)Br(2)O(3), the dihedral angle between the furan-5(2H)-one ring and the benzene ring is 1.2?(3)°. Two intra-molecular C-H?O inter-actions occur in the mol-ecule, both of which generate S(6) rings. The bromo-ethyl fragment is disordered over two sets of sites in a 0.773?(8):0.227?(8) ratio. In the crystal, inversion dimers linked by pairs of C-H?? inter-actions occur.

2-Amino-5-bromo-pyridinium 2-carb-oxy-benzoate.

Project description:The asymmetric unit of the title compound, C(5)H(6)BrN(2) (+)·C(8)H(5)O(4) (-), consists of two crystallographically independent 2-amino-5-bromo-pyridinium cations (A and B) and two 2-carb-oxy-benzoate anions (A and B). Each 2-amino-5-bromo-pyridinium cation is approximately planar, with a maximum deviation of 0.047?(1)?Å in cation A and 0.027?(1)?Å in cation B. The 2-amino-5-bromo-pyridinium unit in cation A is inclined at dihedral angles of 4.9?(3) and 2.2?(3)° with the phenyl rings of the A and B 2-carb-oxy-benzoate anions, respectively. The corresponding angles for cation B are 3.0?(3) and 5.6?(3)°. The mol-ecular structure is stabilized by an intra-molecular O-H?O hydrogen bond,which generates an S(7) ring motif. The cations and anions are linked via inter-molecular N-H?O and C-H?O hydrogen bonds, generating R(2) (2)(8) ring motifs. In the crystal packing, mol-ecules are linked into wave-like chains along [001] via adjacent ring motifs. Short inter-molecular distances between the phenyl and pyridine rings [3.613?(4) and 3.641?(4)?Å] indicate the existence of ?-? inter-actions. The crystal structure is a non-merohedral twin with a contribution of 0.271?(3) of the minor component.
