Reaction of [Ln(CH2SiMe3)3(thf) 2] (Ln = Y, Yb, and Lu) with one equivalent of Me 2Si(C5Me4H)NHR? (R? = Ph, 2,4,6-Me3C6H2) affords straightforwardly the corresponding half-sandwich rare-earth metal alkyl complexes [{Me 2Si(C5Me4)(NR?)}Ln(CH 2SiMe3)(thf)u] (1: Ln = Y, R? = Ph. n = 2: 2: Ln = Y, R? = C6H2Me32,4,6, n = 1; 3: Ln = Y, R? = tBu, n = 1: 4: Ln = Yb. R? = Ph, n = 2: 5: Ln = Lu, R? = Ph, n = 2) in high yields. These complexes, especially the yttrium complexes 1-3. serve as excellent catalyst precursors for the catalytic addition of various primary and secondary amines to carbodiimides, efficiently yielding a scries of guanidinc derivatives with a wide range of substituents on the nitrogen atoms. Functional groups such as C?N, C?CH. and aromatic C-X (X: F, Cl, Br, I) bonds can survive the catalytic reaction conditions. A primary amino group can be distinguished from a secondary one by the catalyst system, and therefore, the reaction of 1,2,3,4-tetrahydro-5-aminoisoquinoline with iPrN=C=NiPr can be achieved stepwise first at the primary amino group to selectively give the monoguanidine 38, and then at the cyclic secondary amino unit to give the biguanidine 39. Some key reaction intermediates or true catalyst species, such as the amido complexes [{Me2Si(C 5Me4)(NPh)}Y(NEt2)(thf)2] (40) and [{Me2Si(C5Me4)(NPh))Y(NHC6H 4Br4)(thf)2] (42), and the guanidinate complexes [{Me 2Si(C5Me4)(NPh)}Y{iPrNC(NEt2)(NiPr)) (thf)] (41) and [{Me2Si(C5Me4)(NPh)}Y(iPrN) C(NC6H4Br-4)(NHiPr))(thf)] (44) have been isolated and structurally characterized. Reactivity studies on these complexes suggest that the present catalytic formation of a guanidine compound proceeds mechanistically through nucleophilic addition of an amido species, formed hy acid-base reaction between a rareearth metal alkyl bond and an amine N-H bond, to a carbodiimide, followed by amine protonolysis of the resultant guanidinate species.

The reaction of 2-(cyanomethyl)benzoic acid with amines RNH2 (R = Ar, Het, CH2Ar, CH2Het) leads to the formation of the corresponding 3-NHR-isoquinolin-1(2H)-ones. When R = CH2Ar and CH2Het, there is a side reaction involving hydrolysis of the hydrolytically-unstable intermediates, derivatives of 2-(2-amino-2-iminoethyl) benzoic acid, leading to 2-R-isoquinoline-1,3(2H,4H)-diones.

The x-ray crystal structure of 3-((5-methylisoxazol-3-yl)amino)-5- methylcyclohex-2-enone (12b) and 3-((5-methylisoxazolyl-3-yl)amino)-5,5- dimethylcyclohex-2-enone (12c) were determined and correlated to their anticonvulsant activity in mice and rats. A hypothesis for the toxicity of the analogs are advanced. In addition, a series of 5-methyl-N-(3-oxocyclohex-1-enyl) -isoxazole-3-carboxamides were synthesized and evaluated for anticonvulsant activity. These compounds were compared to the activity of the corresponding amino and aminomethyl enaminones. Additional investigation involved the synthesis and evaluation of a trifluoromethyl analog of the active isoxazole tert-butyl 4-(5-methisoxazol-3-yl-amino)-6-methyl-2-oxo-cyclohex-3-ene carboxylate (4f).

The presence of antibiotics in treated wastewater and consequently in surface and groundwater resources raises concerns about the formation and spread of antibiotic resistance. Improving the removal of antibiotics during wastewater treatment therefore is a prime objective of environmental engineering. Here we obtained a detailed picture of the fate of sulfonamide antibiotics during activated sludge treatment using a combination of analytical methods. We show that pterin-sulfonamide conjugates, which are formed when sulfonamides interact with their target enzyme to inhibit folic acid synthesis, represent a major biotransformation route for sulfonamides in laboratory batch experiments with activated sludge. The same major conjugates were also present in the effluents of nine Swiss wastewater treatment plants. The demonstration of this biotransformation route, which is related to bacterial growth, helps explain seemingly contradictory views on optimal conditions for sulfonamide removal. More importantly, since pterin-sulfonamide conjugates show retained antibiotic activity, our findings suggest that risk from exposure to sulfonamide antibiotics may be less reduced during wastewater treatment than previously assumed. Our results thus further emphasize the inadequacy of focusing on parent compound removal and the importance of investigating biotransformation pathways and removal of bioactivity to properly assess contaminant removal in both engineered and natural systems.

To improve the physical and chemical properties of phenazine-1-carboxylic acid (PCA) and find higher antifungal compounds, a series of PCA amide analogues were designed and synthesized and their structures were confirmed by 1H NMR, HRMS, and X-ray. Most compounds showed some antifungal activities in vitro. Particularly, compound 3d exhibited inhibition effect against Pyriculariaoryzac Cavgra with EC50 value of 28.7 muM and compound 3q exhibited effect against Rhizoctonia solani with EC50 value of 24.5 muM, more potently active than that of the positive control PCA with its EC50 values of 37.3 muM (Pyriculariaoryzac Cavgra) and 33.2 muM (Rhizoctonia solani), respectively.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of 5-Methylisoxazol-3-amine, you can also check out more blogs about1072-67-9
