Synthesis of furanose derivatives of 3-deoxy-D-erythro-2-hexulosonic acid and their 3-bromo and 3-deuterio analogs.
Methanolysis of 2,4,6-tri-O-benzoyl-2,3-dibromo-3-deoxy-D-altrono-1,5-lactone gave methyl 3-bromo-3-deoxy-2,4,6-tri-O-benzoyl-alpha-D-ribo-hex-2-ulofuranosonat e (3) and the anomeric mixture of the analogous 4,6-di-O-benzoyl derivative, having HO-2 free. Compound 3 was subjected to debromination with tributyltin hydride and tributyltin deuteride in the presence of 2,2'-azo-bisisobutyronitrile a...
متن کاملSulfuric acid {[3-(3-silicapropyl)sulfanyl]propyl}ester as a recyclable solid acid catalyst for the synthesis of α-amino nitriles
Sulfuric acid {[3-(3-silicapropyl)sulfanyl]propyl}ester (SASPSPE) is employed as a recyclable catalyst for the synthesis of α-amino nitriles. These syntheses were performed via a one-pot three-component condensation of aldehydes, amines, and trimethylsilyl cyanide under mild reaction conditions at room temperature. The catalyst could be recycled and reused several times without any loss of effi...

متن کاملA Combined Chemical - En zymatrc Synthesis of 3 - Deoxy - D - arabino - heptulosonic Acid 7 - Phosphate I
3-Deoxy-o-arabino-heptulosonic acid 7-phosphate (DAHP) has been synthesized from N-acetyl-n/l-aspartate p-semialdehyde and dihydroxyacetone phosphate in four steps with an overall yield of 13%. The key step generates the required threo stereochemistry by using rabbit muscle aldolase (E.C.4.1.2.13) as catalysl. 3-Deoxy-o-arabino-heptulosonic a id 7-phosphate (DAHP, l) is an important intermediat...
متن کامل2-Amino-3-nitrobenzoic acid
The title compound, C(7)H(6)N(2)O(4), is approximately planar (r.m.s. deviation = 0.026 Å for the 13 non-H atoms). The mol-ecular structure is stabilized by intra-molecular N-H⋯O hydrogen bonds, which generate S(6) ring motifs. In the crystal, mol-ecules are linked via inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds into a three-dimensional network.
