Direct oxidative amidation of aldehydes with amines catalyzed by heteropolyanion-based ionic liquids under solvent-free conditions via a dual-catalysis process
A simple and efficient procedure for the synthesis of amides directly from aldehydes and amines catalyzed by heteropolyanion-based ionic liquids undersolvent-freeconditions has been reported. The practical protocol was found to tolerate a wide range of substrates with different functional groups. Moderate to excellent yields, solvent-free media, and operational simplicity are the main highlights
An efficient, eco-friendly and sustainable tandem oxidative amidation of alcohols with amines catalyzed by heteropolyanion-based ionic liquids via a bifunctional catalysis process
eco-friendly and sustainable method for the tandem oxidative amidation of alcohols with amines has been reported. Using heteropolyanion-based ionic liquids as the catalyst and tert-butyl hydroperoxide as the oxidant, this amidation reaction is operationally straightforward and provides a series of primary, secondary and tertiary amidesderivatives in moderate to good yields. Solvent-free media, microwave-promoted
A One-Pot tandem Schmidt–Ritter process for the synthesis of amides has been developed using the super acid as catalyst. The in situ generated aryl/aliphatic nitriles from the reaction of aldehydes and sodium azide in the presence of TfOH and AcOH (Schmidt reaction) react with suitable alcohol (Ritter reaction) to give the amides. For the first time we observed that during the Schmidt process N-acylimides

A group of benzamide compounds are disclosed which are useful for treating neurodegenerative disorders. Methods for making these compounds are provided. These materials are formed into pharmaceutical compositions for oral or intravenous administration to patients suffering from conditions such as Parkinson's disease which can exhibit themselves as progressive loss of central nervous system function. The compounds can arrest or slow the progressive loss of function.
The present invention relates to methods of detecting neurodegenerative diseases or disorders, particularly to methods for early detection of neurodegenerative diseases, such as Parkinson's disease. The present invention provides a method for detecting a neurodegenerative disease in a subject, the method comprising testing the subject for an indicator of release of neuromelanin from cells in the brain, wherein a positive test is indicative of death of brain cells containing neuromelanin and is characterised by an elevated level of the indicator of release of neuromelanin compared to control values.
