Ring Cleavage of Some Bicylic Compounds Derived from 1,2,4-Triazine
Ring cleavage occurred when 1,2,4-triazino-1,2,4-triazines (3), (4) and (5) were treated with concentrated hydrochloric acid to yield N-substituted triazines (7) and (8). These confirm the given configuration assigned to the isomeric triazinotriazines. 6-Methyl-2-phenyl-7H-oxazolo [3,2-b][1,2,4]-triazin-7-one (9) underwent ring cleavage on treatment with sodium alkoxide to afford 3-alkoxy-1...

متن کاملAromatic ring cleavage by a Thiobacillus.
As part of a study on the assimilation of organic compounds by autotrophic microorganisms, enrichment cultures were set up for thiobacilli. A facultatively autotrophic Thiobacillus was isolated in pure culture and grew heterotrophically on many organic compounds including p-hydroxybenzoate (PHBz). Since degradation of aromatic compounds is carried out by a limited range of bacterial genera, the...
متن کاملThe 7-connected Cobordism Ring
In this paper, we study the cobordism spectrum MO〈8〉 at the prime 3. This spectrum is important because it is conjectured to play the role for elliptic cohomology that Spin cobordism plays for real K-theory. We show that the torsion is all killed by 3, and that the Adams-Novikov spectral sequence collapses after only 2 differentials. Many of our methods apply more generally.
متن کاملBacterial metabolism of 5-aminosalicylic acid. Initial ring cleavage.
The metabolism of 5-aminosalicylate (5AS) by a bacterial strain, Pseudomonas sp. BN9, was studied. Intact cells of Pseudomonas sp. BN9 grown with 5AS oxidized 5AS and 2,5-dihydroxybenzoate (gentisate), whereas cells grown with gentisate oxidized only the growth substrate of all substituted salicylates tested. Cell extracts from Pseudomonas sp. BN9 catalysed the stoichiometric reaction of 1 mol ...
