Primary hypertriglyceridemias are very rare in pediatric age group. A case of 12 years old boy with hypertriglyceridemia is presented. He was being treated as a case of thalassemia major since 2 years of age and was picked up incidentally when his serum turned milky on standing. Since hypertriglyceridemia is a known risk factor for the acute pancreatitis so… (More)
The complete molecule of the title compound, C(24)H(30)O(6), is generated by a crystallographic inversion centre. In the unique part of the mol-ecule, the four-atom -O-CH(2)-C(= O)-O- chain between the benzene ring and the tert-butyl group assumes a zigzag conformation [O-C-C-O torsion angle = -162.3 (1)°].
In the crystal structure of the title compound, C(16)H(14)O(6)·H(2)O, the dihedral angle between the benzene rings is 60.8 (3)°. Mol-ecules are linked through a bifurcated O-H⋯O hydrogen bond, forming a zigzag chain along the b axis. The chains are further linked by O-H⋯O hydrogen bonds mediated by water mol-ecules.
In the mol-ecule of the title compound, C(29)H(40)O(6), the carbon atom belonging to the propyl chain is connected to two aromatic rings that open up the C(ar-yl)-C-C(ar-yl) angle to 111.5 (1)°. The four-atom -O-CH(2)-C(=O)-O- linkage between the aromatic ring and the tert-butyl group assumes a (-)anti-periplanar conformation for one substituent and a… (More)
In the title mol-ecule, C(12)H(15)NO(5), the nitro-phen-oxy portion is approximately planar (r.m.s. deviation = 0.034 Å) and makes an angle of 84.8 (1)° with respect to the -CH(2)-C(=O)-O-C fragment. In the crystal, π-π stacking is observed between nearly parallel benzene rings of adjacent mol-ecules, the centroid-centroid distance being 3.6806 (10) Å. Weak… (More)
In the title compound, C(20)H(22)O(6), the mean planes through the benzene rings make a dihedral angle of 59.82 (7)° with each other. Weak inter-molecular C-H⋯O inter-actions together with π-π stacking inter-actions [centroid-centroid distance = 3.830 (1) Å] between benzene rings are observed in the crystal packing.
The title compound, C(24)H(30)O(6), does not exhibit π-π inter-actions due to the steric effect of the bulky tert-butyl groups present in the mol-ecule. The presence of these groups at the 2 and 2' positions hinders the free motion of the benzene rings relative to each other, causing them to adopt an anti-periplanar arrangement. The benzene rings are… (More)
In the title compound, C(33)H(36)O(6), two naphthalene ring systems are connected through a methyl-ene linkage [C-C-C = 114.9 (2)°]; the ring systems are aligned at an angle of 76.5 (1)°. Of the two -O-CH(2)-C(=O)-C(CH(3))(3) substituents, one adopts an extended conformation whereas the other is U-shaped. In the crystal, mol-ecules are linked via weak C-H⋯O… (More)
There are one-and-a-half independent mol-ecules in the asymmetric unit of the title compound, C(18)H(20)N(2)O(4). One mol-ecule is centrosymmetric with the mid-point of the N-N bond located on a center of inversion. In the other, which lies on a general position, the benzene rings are aligned at 21.6 (1)°. Weak inter-molecular C-H⋯O hydrogen bonding is… (More)
