3-tert-Butyl 5-methyl (2R,4S,5R)-2-(4-methoxyphenyl)-4-(3-nitrophenyl)-1,3-oxazolidine-3,5-dicarboxylate.

ABSTRACT: The title mol-ecule, C(23)H(26)N(2)O(8), was synthesized in three steps starting from m-nitro-cinnamic acid. The central oxazolidine ring adopts an almost perfect envelope conformation with the O atom as the flap [puckering parameter ? = 0.3?(6)°]. The dihedral angle formed by the benzene rings is 61.81?(9)°. In the crystal, mol-ecules are connected into double chains parallel to [010] by C-H?O hydrogen bonds. The absolute configuration was assigned from the synthetic procedure.

N-[2-(2-Methoxyphenyl)benzylidene]-tert-butyl-amine N-oxide.

Project description:In the mol-ecule of the title compound, C(18)H(21)NO(2), the two benzene rings are oriented at a dihedral angle of 58.19?(3)°. Intra-molecular C-H?O hydrogen bonds result in the formation of one six- and one five-membered ring, which adopt twist and envelope conformations, respectively. In the crystal structure, C-H?O hydrogen bonds link the mol-ecules.

(3,5-Di-tert-butyl-2-eth-oxy-benzyl-idene)[2-(3,5-di-tert-butyl-1H-pyrazol-1-yl)eth-yl]amine.

Project description:The angles within the benzene ring in the title compound, C(30)H(49)N(3)O, ranging from 116.34 (16) to 124.18 (16)°, reflect the presence of electron-donating and electron-withdrawing substituents. The angles at the two electron-donating tert-butyl substituents are smaller than 120°, at the electron-withdrawing eth-oxy substituent larger than 120°, and at the imine substituent equal to 119.59 (16)°. The latter does not reflect the electron-donating nature of the imine group due to the presence of other substituents.

Project description:The title oxazolidine compound, C(27)H(39)NO(2), was synthesized from N-isopropyl-norephedrine. The dihedral angle between the aromatic rings is 70.33?(5)°. The N atom of the heterocycle is oriented to allow intra-molecular O-H?N hydrogen bonding with the hydr-oxy substituent.

(1R*,2R*,4S*,5R*,6R*,8S*)-4,8-Dimethyl-2,6-diphenyl-bicyclo-[3.3.1]nonane-2,6-diol.

Project description:The racemic title compound, C(23)H(28)O(2), crystallizes in the space group C2/c as a layered structure in which a centrosymmetric three hydrogen bond sequence links four molecules. Both hydroxy groups are involved in this arrangement, but they differ in that one participates in two hydrogen bonds while the other takes part in only one. Between layers, the aromatic rings take part in edge-face interactions [shortest C-H⋯C distances 3.04, 3.10 and 3.12 Å and angle between normal to planes 86.7(2)°], forming a centrosymmetric dimer. The lattice is further stabilized by C-H⋯π interactions involving both methyl (shortest C⋯C 3.82 and 3.97 Å) and methylene (shortest C⋯C 3.60 Å) groups.

2,4-Di-tert-butyl-6-[(R/S)-1-(3,5-di-tert-butyl-2-hy-droxy-phen-yl)eth-yl]phenyl [(1R,4S)-7,7-dimethyl-2-oxobicyclo-[2.2.1]heptan-1-yl]methane-sulfonate.

Project description:The asymmetric unit of the title compound, C(40)H(60)O(5)S, comprises two diastereomers related, except for the chiral camphor groups, by a pseudo-inversion centre. In both diasteromers, the camphor sulfate moiety maintained the absolute configuartion (R,S) of the precursor. However, the absolute configurations at the methine C atoms are of opposite chirality. Both mol-ecules reveal intra-molecular O-H?O hydrogen bonds, whereas van der Waals inter-actions define the crystal packing.

Phenyl 3,5-di-tert-butyl-2-hy-droxy-benzoate.

Project description:The title mol-ecule, C(21)H(26)O(3), has a six-membered planar carbon ring as the central core, substituted at position 1 with phen-oxy-carbonyl, at position 2 with hy-droxy and at positions 3 and 5 with tert-butyl groups. The structure shows two independent but very similar mol-ecules within the asymmetric unit. For both independent mol-ecules, the ester carboxyl-ate group is coplanar with the central core, as reflected by the small C-C-O-C torsion angles [179.95?(17) and 173.70?(17)°]. In contrast, the phenyl substituent is almost perpendicular to the carboxyl-ate -CO(2) fragment, as reflected by C-O-C-C torsion angles, ranging from 74 to 80°. The coplanarity between the central aromatic ring and the ester carboxyl-ate -CO(2)- group allows the formation of an intra-molecular hydrogen bond, with O?O distances of 2.563?(2) and 2.604?(2)?Å.

Dichloridobis[(1S,1S',2R,2R')-(+)-1,1'-di-tert-butyl-2,2'-diphospho-lane-?P,P']ruthenium(II).

Project description:In the title compound, [RuCl(2)(C(16)H(32)P(2))(2)], the Ru(II) ion is situated on a twofold rotation axis, so the asymmetric unit contains one half-mol-ecule. The slightly distorted octa-hedral environment of the Ru center is formed by four P atoms [Ru-P = 2.4417?(6) and 2.4544?(6)?Å] from two different (1S,1S',2R,2R')-TangPhos ligands [(1S,1S',2R,2R')-TangPhos = (1S,1S',2R,2R')-(+)-1,1'-di-tert-butyl-2,2'-diphospho-lane] and two Cl atoms [Ru-Cl = 2.4267?(5)?Å].

Di-tert-butyl 3,5-dimethyl-1H-pyrrole-2,4-dicarboxyl-ate.

Project description:In the title mol-ecule, C(16)H(25)NO(4), the non-H atoms, except for the two tert-butyl groups, are roughly planar (r.m.s. deviation of the non-H atoms = 0.086 Å). In the crystal, mol-ecules are linked into inversion dimers by pairs of N-H⋯O hydrogen bonds, forming R(2) (2)(10) ring motifs.
