6-[Bis(ethoxycarbonyl)methyl]-6-deoxy-1,2;3,4-di-O-isopropylidene-d-galactopyranose
The title compound, C(19)H(30)O(9), was prepared by substitution at the C6 position in 1,2;3,4-di-O-isopropyl-idene-6-O-trifluoro-methane-sulfonyl-d-galactose using sodium eth-oxy-malonate in dimethyl-formamide. The conformation is skew-boat (0)S(2), slightly distorted towards boat B(2,5). The inflexible pyran-ose structure makes the title compound a suitable inter-mediate for further synthetic...
متن کامل2-Methyl-6-nitro-2H-indazole
In the title compound, C(8)H(7)N(3)O(2), the mol-ecular skeleton is almost planar with a maximum deviation of 0.0484 (9) Å for the methyl C atom. In the crystal, weak inter-molecular C-H⋯N and C-H⋯O hydrogen bonds help to establish the packing.
متن کامل1-Methyl-6-nitro-1H-benzimidazole
The title compound, C(8)H(7)N(3)O(2), a potential anti-tumour drug and an anti-oxidant agent, was studied in order to give more insight into structure-function relationships. The 1-methyl-benzimidazole unit of the mol-ecule was found to be exactly planar and the nitro group is inclined at an angle of 10.4 (2)° to the plane of the heterocycle. The bond lengths in the present derivative were anal...
متن کاملBorate esters of the methyl D-glucopyranosides.
Methyl alpha- and beta-D-glucopyranoside act as moderate chelators of a boron centre through their O-4/6 binding site whereas the trans/trans arrangement of the O-2/3/4 hydroxy functions is not suited to form a chelate with the small boron central atom. In this work we report the crystal structure of the bisdiolatoborate Na2[B(Me alpha-D-Glcp4,6H(-2))(Me alpha-D-Glcp3,4,6H(-3))].NaOH.8H2O (1) a...
متن کامل1-Methyl-2-methylsulfanyl-6-nitro-1H-benzimidazole
The mol-ecule of the title compound, C9H9N3O2S, is built up from fused five- and six-membered rings connected to methyl-sulfanyl and nitro groups, respectively. The mean plane through the fused ring system is inclined slightly relative to the plane passing through the nitro group [dihedral angle = 3.6 (2)°]. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds and π-π inter-actions bet...
