Application of 2-methylpyridinum p-toluenesulfonate ([2-MPy][p-TSA]) as an efficient catalyst for the one-pot synthesis of hexahydroquinolines-3-carboxamides
2-Methylpyridinum p-toluenesulfonate ([2-MPy][p-TSA]) as a novel room temperature ionic liquidwas synthesized and evaluated as a recoverable catalyst for the one-pot synthesis ofhexahydroquinoline-3-carboxamide derivatives by four-component reaction of arylaldehydes,dimedone, acetoacetanilide and ammonium acetate in high to excellent yield in ethanol at 50 oC.The [2-MPy]...
متن کاملCharacterization of the p-toluenesulfonate operon tsaMBCD and tsaR in Comamonas testosteroni T-2.
Comamonas testosteroni T-2 uses a standard, if seldom examined, attack on an aromatic compound and oxygenates the side chain of p-toluenesulfonate (TS) (or p-toluenecarboxylate) to p-sulfobenzoate (or terephthalate) prior to complete oxidation. The expression of the first three catabolic enzymes in the pathway, the TS methyl-monooxygenase system (comprising reductase B and oxygenase M; TsaMB), ...
متن کاملN-(2-Amino-3,5-dibromobenzyl)-N-methylcyclohexan-1-aminium p-toluenesulfonate
The title compound, C(14)H(21)Br(2)N(2) (+)·C(7)H(7)O(3)S(-), features a salt of protonated bromhexine, a pharmaceutical used in the treatment of respiratory disorders, and the p-toluenesulfonate anion. The crystal packing is stabilized by inter-molecular N-H⋯O, N-H⋯Br and C-H⋯O hydrogen bonds.
متن کاملCharacterization of TsaR, an oxygen-sensitive LysR-type regulator for the degradation of p-toluenesulfonate in Comamonas testosteroni T-2.
TsaR is the putative LysR-type regulator of the tsa operon (tsaMBCD) which encodes the first steps in the degradation of p-toluenesulfonate (TSA) in Comamonas testosteroni T-2. Transposon mutagenesis was used to knock out tsaR. The resulting mutant lacked the ability to grow with TSA and p-toluenecarboxylate (TCA). Reintroduction of tsaR in trans on an expression vector reconstituted growth wit...
متن کاملA Sensitive and Simple HPLC-UV Method for Trace Level Quantification of Ethyl p-Toluenesulfonate and Methyl p-Toluenesulfonate, Two Potential Genotoxins in Active Pharmaceutical Ingredients
A sensitive and simple HPLC/UV method has been developed and validated for the determination of two potential genotoxic impurities, namely methyl p-toluenesulfonate (MPTS) and ethyl p-toluenesulfonate (EPTS) at trace levels in Pemetrexed sodium API. Applying the concept of threshold of toxicological concern (TTC), a limit of 3 ppm each for both genotoxins was calculated based on the maximum dai...
