Polyethylene glycol (PEG-400): an efficient and recyclable reaction medium for the synthesis of pyrazolo[3,4-b]pyridin-6(7H)-one derivatives.
A mild and efficient synthesis of pyrazolo[3,4-b]pyridine-6(7H)-one derivatives via a three-component reaction of an aldehyde, Meldrum's acid and 3-methyl-1H-pyrazol-5-amine using recyclable polyethylene glycol (PEG)-400 as a reaction medium is described. This method has the advantages of accessible starting materials, good yields, mild reaction conditions and begin environmentally friendly.
متن کاملImmunogenicity of Polyethylene Glycol (PEG)
Covalent attachment of polyethylene glycol (PEG) to active proteins (PEGylation technology) successfully generated several FDA-approved compounds, including four blockbusters, which are considered non immunogenic. However, PEG antibodies and intolerance to the infusion were reported in some patients with gout treated with pegloticase, a PEG-uricase recently approved by the FDA (Food and Drug Ad...
متن کاملStability of Trinitroglycerin in Polyethylene Glycol 400
In this study, the stability of trinitroglycerin (TNG) in polyethylene (PEG) 400 was investigated according to Arrhenius approach. The reaction rate constant (k) for the thermal disintegration of TNG in PEG 400 at various temperatures was counted based on the percents of remaining TNG at different intervals of time at a specific temperature. The results showed that “k” at 40, 50, 60, 70, 8...
متن کاملPolyethylene glycol embedded tribromide as an efficient and reusable catalyst for the library synthesis of nitrogen containing heterocycles
Potassium tribromide wrapped around polyethylene glycol ({K+PEG400}Br3-) was easily prepared by two step reaction of PEG400 with KBr followed by the addition of molecular bromine to give PEG embedded potassium tribromide as a dark viscous oil. The synthesized material was found to be an efficient, cost effective, environmentally benign and recyclable catalyst for the library synthesis of nitrog...
