(2S,4′R,5′R)-(E)-tert-Butyl 2-acetyl-2-(2-oxo-5-phenyl-1,3-dioxolan-4-ylmethyl)-5-phenylpent-4-enoate
The title compound, C(27)H(30)O(6), was prepared by monodihydroxy-lation of the bis-olefin (E,E)-tert-butyl 2-acetyl-2-cinnamyl-5-phenyl-pent-4-enoate using standard Sharpless asymmetric dihydroxy-lation conditions, followed by treatment with 1,1'-carbonyl diimidazole. In the crystal structure, the phenyl rings form an intra-molecular edge-to-face C-H⋯π contact with an inter-planar angle of 56....
متن کاملEthyl 1-tert-butyl-5-phenyl-1H-pyrazole-4-carboxylate
In the title compound, C(16)H(20)N(2)O(2), the pyrazole ring is essentially planar [maximum deviation = 0.008 (2) Å] and is inclined at an angle of 82.82 (10)° with respect to the phenyl ring. The crystal packing is consolidated by pairs of inter-molecular C-H⋯O hydrogen bonds, which link the mol-ecules into centrosymmetric dimers stacked along the a axis.
متن کامل4-(5-tert-Butyl-1,3-dithian-2-yl)-5-chloro-2-phenyl-1,3-oxazole
In the title mol-ecule, C(17)H(20)ClNOS(2), the phenyl and oxazole rings are nearly coplanar with an average deviation of 0.022 Å from the mean plane (M). The 1,3-dithiane ring adopts a chair conformation and is twisted in such a way that the C-C(Bu) fragment lies in M (deviations are 0.031 and 0.010 Å, respectively, for the two C atoms).
متن کاملCrystal structure of 1,3-bis(3-tert-butyl-2-hydroxy-5-methylbenzyl)-1,3-diazinan-5-ol monohydrate
In the title hydrate, C28H42N2O3·H2O, the central 1,3-diazinan-5-ol ring adopts a chair conformation with the two benzyl substituents equatorial and the lone pairs of the N atoms axial. The dihedral angle between the aromatic rings is 19.68 (38)°. There are two intra-molecular O-H⋯N hydrogen bonds, each generating an S(6) ring motif. In the crystal, classical O-H⋯O hydrogen bonds connect the 1,...
متن کامل1-[(E)-2-(5-tert-Butyl-2-hydroxyphenyl)diazen-1-yl]naphthalen-2-ol
The non-H atoms of the title compound, C20H20N2O2, is located on a mirror plane except two methyl groups of the tert-butyl group. Intra-molecular N-H⋯O hydrogen bonds exist between the hy-droxy and diazenyl groups. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds into supra-molecular chains running along the a-axis direction.
