1,4-Di-tert-butyl (2R,3R)-2-({(2E)-3-[4-(acet-yloxy)phen-yl]prop-2-eno-yl}-oxy)-3-hy-droxy-butane-dioate.

ABSTRACT: The title compound, C(23)H(30)O(9), has an approximate T-shape with the tert-butyl ester groups lying either side of the benzene ring. The acetyl group is almost perpendicular to the benzene ring to which it is connected [C-C-O-C torsion angle = -106.7?(3)°]. The conformation about the C=C double bond [1.331?(4)?Å] is E. Linear supra-molecular chains along the a axis mediated by hy-droxy-carbonyl O-H?O hydrogen bonds feature in the crystal packing. The same H atom is also involved in an intra-molecular O-H?O inter-action.

Project description:In the title mol-ecule, C(24)H(32)O(10), one tert-butyl ester group is folded towards the central benzene ring while the other is directed away. The acetyl group is almost perpendicular to the benzene ring to which it is connected [C-C-O-C torsion angle = 90.4?(12)°]. The conformation about the ethene bond [1.313?(7)?Å] is E. The atoms of the benzene ring and its attached ester group and part of the hy-droxy tert-butyl ester side chain are disordered over two sets of sites in a 50:50 ratio. Linear supra-molecular chains along the a axis mediated by hy-droxy-carbonyl O-H?O hydrogen bonds feature in the crystal packing. The same H atom also partakes in an intra-molecular O-H?O inter-action.

Crystal structure of [(2R,3R,4S)-3,4-bis(acet-yloxy)-5-iodo-3,4-di-hydro-2H-pyran-2-yl]methyl acetate.

Project description:In the title compound, C12H15IO7, the 3,4-di-hydro-2H-pyran ring is in a distorted half-boat conformation with the atom bearing the acet-yloxy group adjacent to the C atom bearing the methyl-acetate group lying 0.633 (6) Å above the plane of the remaining ring atoms (r.m.s. deviation = 0.0907 Å). In the crystal, mol-ecules are linked into a supra-molecular chain along the a axis through two C-H⋯O inter-actions to the same acceptor carbonyl O atom; these chains pack with no specific inter-molecular inter-actions between them.

Project description:The title compound, C(17)H(24)NO(5)S(+)·C(18)H(13)O(8) (-), is the key inter-mediate during the preparation of lesatropane [systematic name (1R,3S,5R,6S)-6-acetoxy-3-(4-methylphenylsulfonyloxy)tropane], a potential anti-glaucoma agent. The tertiary N atom of the tropane ring is involved in inter-molecular N-H?O hydrogen bonding, and the carboxylate groups are involved in inter-molecular O-H?O hydrogen bonding.

(1R,2R,3R,4R,5S)-2,3-Bis[(2S')-2-acet-oxy-2-phenyl-acet-oxy]-4-azido-1-[(2,4-dinitro-phen-yl)hydrazono-meth-yl]bicyclo-[3.1.0]hexa-ne.

Project description:In the title compound, C(38)H(29)N(7)O(12), the five-membered ring adopts an envelope conformation in which the 'flap' is cis to the cyclo-propane group. This conformation is similar to those of other bicyclo-[3.1.0]hexane analogues for which crystal structures have been reported. The absolute configuration of the stereogenic centers on the cyclo-pentane ring, as determined by comparison with the known configurations of the stereogenic centers in the (2S)-2-acet-oxy-2-phenyl-acet-oxy groups, is 1(R), 2(R), 3(R), 4(R) and 5(S). An intramolecular N-H⋯O hydrogen bond is present.

N'-[(2E)-3-Phenyl-prop-2-eno-yl]benzo-hydrazide.

Project description:In the title compound, C(16)H(14)N(2)O(2), the conformation about the C=C bond is E, and the two amide groups are effectively orthogonal [the C-N-N-C torsion angle is 104.5 (2)°]. In the crystal structure, the amide groups groups associate via N-H⋯O hydrogen bonding, forming supra-molecular tapes with undulating topology along the c-axis direction.

In the crystal, supra-molecular layers in the ac plane are formed through C-H?O and C-H??(triazole) inter-actions. These stack along the b axis being connected by C-H?N contacts.

The nitro group is nearly coplanar with the benzene ring [dihedral angle = 2.5?(2)°]. In the crystal, the components are linked by N-H?O, O-H?N and O-H?O hydrogen bonds, generating supra-molecular layers parallel to (001).
