organic compounds
The title compound, C18H18B2O6, was formed by the reaction between phenylboronic acid and D-glucose. The structure is analogous to those of D-glucoboronates previously prepared and characterized by NMR. In the crystal structure, molecules are linked into one-dimensional chains along [100] via O—HO hydrogen bonds [OO = 2.8283 (17) Å].
organic compounds
The title compound, C13H16Cl2N4O4S, was formed by base-assisted N-alkylation of [2-(3,5-dichlorophenyl)-1,1-dioxo-2,3-dihydro-1H-1λ6-1,2,3,5-thiatriazol-4-yl]dimethylamine with methyl 2-bromopropanoate, followed by a novel base-promoted ring-expansion reaction, to form a relatively rare 1,1-dioxo-1,2,4,6-thiatriazine. The thiatriazine heterocycle adopts an envelope conformation. In the crystal structure, adjacent molecules are linked by an N—HO hydrogen bond to form chains parallel to the a direction.
