The crystal structure of the title compound (24DMPBA), C(15)H(14)O(2), resembles those of 4-methyl-phenyl benzoate, 2,3-dimethyl-phenyl benzoate and other aryl benzoates, with similar bond parameters. The central -O-C-O- group in 24DMPBA makes dihedral angles of 85.81 (5) and 5.71 (13)°, respectively, with the benzoyl and phenyl rings, while the two aromatic rings form a dihedral angle of 80.25...

The structure of the title compound, C(14)H(13)BrO(2), which contains a norbornenyl group and a 4-bromo-benzoate ester at the single C-atom bridge, has been redetermined [see McDonald & Trotter (1965 ▶). Acta Cryst.19, 456-463] to modern standards to establish high-precision geometrical data to compare with norbornyl and other tetra-cyclic 4-bromo-benzoates. Possible structural evidence is soug...

scyllo-Inositol is the all equatorial stereoisomer of myo-inositol. All possible 12 regioisomers of scyllo-inositol phosphate were synthesized for the first time via a scyllo-inositol benzoate intermediate, which was derived from a myo-inositol derivative. The stereoinversion of myo-inositol into scyllo-inositol was accomplished by Mitsunobu reaction of the vicinal cis-diol. The requisite inter...

A series of ethyl 4-(2-aryloxyhexyloxy)benzoates was prepared and tested for their activity to induce precocious metamorphosis in larvae of the silkworm. Phenyl analog 5 showed activity comparable to that of the 6-methyl-3-pyridyl analog reported as a novel anti-JH agent. The activity of 5 could be fully counteracted by methoprene, a JH agonist. The ethoxycarbonyl group of 5 was essential for i...

The title compound, [Zn(C(7)H(4)FO(2))(2)(C(6)H(6)N(2)O)(2)]·H(2)O, is a monomeric complex. It contains two 4-fluoro-benzoate and two nicotinamide ligands and one uncoordinated water mol-ecule. The 4-fluoro-benzoates act as bidentate chelating ligands, while the nicotinamides are monodentate. The six-coordinate geometry around the Zn(II) atom may be described as highly distorted octa-hedral, wi...

The crystal structure of the title compound, C(13)H(8)Cl(2)O(2), resembles those of 2,3-dichloro-phenyl benzoate, 2,4-dimethyl-phenyl benzoate and other aryl benzoates, with similar bond parameters. The plane of central -C(=O)-O- group is inclined at the angle of 9.1 (2)° with respect to the benzoate ring. The two aromatic rings make a dihedral angle of 47.8 (1)°. In the crystal structure there...

The crystal structure of the title compound 3CP4MBA, C(14)H(11)ClO(2), resembles those of 3-methyl-phenyl 4-methyl-benzoate (3MP4MBA), 4-methyl-phenyl 4-methyl-benzoate (4MP4MBA), 4-methyl-phenyl 4-chloro-benzoate (4CP4MBA) and other aryl benzoates with similar bond parameters. The dihedral angle between the benzene rings in 3CP4MBA is 71.75 (7)°, compared with 56.82 (7)° in 3MP4MBA and 63.57 (...
