  • 7-(4-Bromobutoxy)-3,4-dihydroquinolin-2-one

    CAS:
    7-(4-Bromobutoxy)-3,4-dihydroquinolin-2-one is a palladium catalyst that can be used in a Buchwald reaction. This reaction is an industrially scalable process that has been developed to produce high yields of valuable organic compounds from inexpensive starting materials. The catalytic cycle involves the formation of the palladium species Pd(0) followed by its oxidative addition to an alkyl halide. This addition leads to the formation of a palladium(II) species and subsequent reductive elimination of hydrogen halide. 7-(4-Bromobutoxy)-3,4-dihydroquinolin-2-one is used as a catalyst in this process because it selectively reacts with electron rich aromatic substrates to form substituted benzoquinones or phenols. The product distribution is determined by the reactivity of the substrate and the relative rates of competing reactions. Impurities are formed during synthesis due to

  • 5-Methyl Zolpidem

    CAS:
    5-Methyl Zolpidem is a zolpidem tartrate that is used for the treatment of insomnia and as a sedative. It is an intermediate in the synthesis of zolpidem tartrate, which is synthesized from 5-methyl-1-(4-methoxybenzoyl)-1H-benzo[d]imidazole with potassium t-butoxide. The synthesis starts with the conversion of 5-methyl-1-(4-methoxybenzoyl)-1H-benzo[d]imidazole to 1-(4'-methylphenyl) benzene by reaction with methyl iodide followed by hydrolysis of the ester group to form 1-(4'-methylphenyl) benzene. The next step involves a nucleophilic substitution reaction using potassium t-butoxide to produce 1-(4'-methylphenyl) benzene t-butoxide, followed by reaction with methanol

  • 3-[Methyl(phenylmethyl)amino]-1-phenyl-1-propanone hydrochloride

    CAS:
    Nisoxetine is a norepinephrine (NE) reuptake inhibitor that is used as an antidepressant. It has been shown to be a potent and selective NE reuptake inhibitor with a high affinity towards the NE transporter in rat brain synaptosomes, with potency several times higher than that of tricyclic antidepressants. Nisoxetine's major advantage over other antidepressants is its high efficiency, which makes it suitable for large-scale production. The synthesis of nisoxetine involves two steps: 1) reaction of 3-[methyl(phenylmethyl)amino]-1-phenyl-1-propanone hydrochloride with toluene to form the corresponding methyl ester and 2) hydrogenation of the methyl ester to form nisoxetine. This synthesis is efficient, stable, and chiral due to the use of bimetallic catalysts.

  • Tenofovir isoproxil monoester

    CAS:
    Tenofovir isoproxil monoester is a prodrug of Tenofovir, which is an antiviral drug. Tenofovir prevents the growth of HIV by interfering with the synthesis of viral DNA. The process development stage involves converting Tenofovir to its disoproxil monoester form, which has been shown to have greater antiviral activity than Tenofovir alone. This conversion process involves condensing one molecule of fumarate with two molecules of tenofovir, forming tenofovir disoproxil fumarate (TFD). TFD can be converted back to Tenofovir using hydrolysis and hydrogenation. Impurities in TFD include isopropyl tenofovir and unidentified impurities that are not present in the parent drug, tenofovir. Tenofovir Disoproxil Fumarate was also shown to be more potent than TFD and is undergoing clinical trials for

  • Pravastatin lactone

    CAS:

    Pravastatin lactone is a prodrug of pravastatin that is hydrolyzed in vivo to its active form. It is used for the treatment of bowel disease and has been shown to have concentration-time curves that are linear and dose-dependent. Pravastatin lactone has an acidic pH, which may be due to the presence of carboxyl groups on the molecule. This drug also inhibits the activity of 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase, which is an enzyme that catalyzes the conversion of HMG CoA to mevalonate in order to produce cholesterol. Pravastatin lactone also suppresses the production of fatty acids by inhibiting their synthesis at the level of acetyl-coenzyme A (acetyl-CoA). The drug has not shown any evidence of toxicity when administered to rats at doses up to 10 mg/kg body weight per day
