ring cleavage of some bicylic compounds derived from 1,2,4-triazine
نویسندگان
چکیده
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-1,2,4-triazines (10). treatment of (9) with concentrated hydrochloric acid gave 6-methyl-2-phenacyl-1,2,4-triazin-3,5(4h)-dione (6). under basic conditions, degradation of (9) occurred followed by ring closure of an intermediate to give 1-amino-4-phenylimidazole-2(3h)-one (11)

متن کاملArthrobacter aurescens TC1 metabolizes diverse s-triazine ring compounds.
Arthrobacter aurescens strain TC1 was isolated without enrichment by plating atrazine-contaminated soil directly onto atrazine-clearing plates. A. aurescens TC1 grew in liquid medium with atrazine as the sole source of nitrogen, carbon, and energy, consuming up to 3,000 mg of atrazine per liter. A. aurescens TC1 is metabolically diverse and grew on a wider range of s-triazine compounds than any...
متن کاملThe degradative pathway of the s-triazine melamine. The steps to ring cleavage.
1. The degradative pathway of melamine (1,3,5-triazine-2,4,6-triamine) was examined in Pseudomonas sp. strain A. 2. The bacterium grew with melamine, ammeline, ammelide, cyanuric acid or NH+4 as sole source of nitrogen, and each substrate was entirely metabolized. Utilization of ammeline, ammelide, cyanuric acid or NH+4 was concomitant with growth. But with melamine as substrate, a transient in...
متن کاملGene sequence and properties of an s-triazine ring-cleavage enzyme from Pseudomonas sp. strain NRRLB-12227.
Pesticides based on the s-triazine ring structure are widely used in cultivation of food crops. Cleavage of the s-triazine ring is an important step in the mineralization of s-triazine compounds and hence in their complete removal from the environment. Cyanuric acid amidohydrolase cleaves cyanuric acid (2,4,6-trihydroxy-s-triazine), which yields carbon dioxide and biuret; the biuret is subject ...

متن کاملPhotoinduced reductive cleavage of some chlorobenzylic compounds. New insights from comparison with electrochemically induced reactions.
The photoinduced reductive cleavage of the carbon-chlorine bond in some chlorobenzylic nitro- and cyano-substituted compounds has been studied by transient absorption spectroscopy. The influence of the nature of the electroattractive group as well as its relative position and of the mixture composition of the solvent were investigated to give new clues into the mechanisms and into the factors t...
