1,5-Anhydro-3,6-di-O-benzyl-2-deoxy-1,2-C-dichloromethylene-d-glycero-d-gulo-hexitol
In the title compound, C(21)H(22)Cl(2)O(4), the pyranosyl ring adopts a twist-boat conformation with the O-benzyl groups in equatorial positions. In the crystal, O-H⋯O hydrogen bonding results in infinite chains of mol-ecules along [100]. The structure is further consolidated by weak C-H⋯O, C-H⋯Cl and C-H⋯π inter-actions. The absolute structure was determined.
متن کاملThe Relationship of Vitamin D and Calcium level with Preeclampsia Severity: A Case- control Study
Background Vitamin D deficiency is associated with physiologic changes that are similar to pathogenesis of preeclampsia. Although association of vitamin D and preeclampsia has been studied previously, their results are not consistent. The aim of this study was to investigate the relationship of serum vitamin D and calcium with preeclampsia severity. Materials and Methods: This case- control st...
متن کاملSynthesis of polyhydroxy amino acids based on D- and L-alanine from D-glycero-D-gulo-heptono-1,4-lactone.
2-Amino-2,3-dideoxy-D-manno-heptonic acid (7) has been synthesized from 2,5,6,7-tetra-O-acetyl-3-deoxy-D-gluco-heptono-1,4-lactone (1), which was readily prepared from D-glycero-D-gulo-heptono-1,4-lactone. O-Deacetylation of 1 followed by treatment with 13:1 (v/v) 2,2-dimethoxypropane/acetone in the presence of p-toluenesulfonic acid gave methyl 3-deoxy-4,5:6,7-di-O-isopropylidene-D-gluco-hepto...
متن کاملEffect of Phototherapy on Serum Level of Calcium, Magnesium and Vitamin D in Infants with Hyperbilirubinemia
Background and Objective: Phototherapy is one of the therapy methods for jaundice caused by hyperbilirubinemia. Vitamin D and bilirubin have two distinct routes of metabolism yet part of their syntheses is common in the liver and thus they may influence each other’s synthesis. One of the consequences of phototherapy not previously studied in detail is hypocalcaemia and hypomagn...
متن کاملKinetics Influence of Operation Conditions on Crystal Growth of Calcium Nitrate Tetrahydrate in a Circulating Fluidized Bed
In order to improve the traditional freezing crystallization process of calcium nitrate in nitric phosphate process, crystal growth experiments by adding Ca(NO3)2·4H2O seeds in supersaturated calcium nitrate solution in a Circulating Fluidized Bed (CFB) crystallizer were carried out on crystal growth kinetics. The results showed that the growth of C...
