TBAI/TBHP mediatedoxidativecrosscoupling of phenols and carboxylic acids with ketones has been reported under metal-free, base free, solvent free conditions enabling environmentally benign synthesis of aryloxyketones, acyloxy ketones and benzofurans. Phenoxyketones and acyloxylcarbonyl compounds were synthesized in good to high yields, where as benzofurans were synthesized in moderate yields. This

The invention relates to novel arylalkenylpropargylamine derivatives of general formula (I) or enantiomers or diastereomers thereof or salts, optionally pharmaceutically acceptable salts, or solvates of any of these. The compounds can be used in treating or preventing a disease or condition in a mammal related to monoamine oxidase dysfunction, especially in neurodegenerative diseases, e.g. Parkinson's disease, Alzheimer's disease or Huntington's disease.

The preparation of 2-(1,3-diazacycloalkenyl)-2-hydrazones of 1-(substituted 2-benzofuranyl)-3-(substituted aryl)-2-propen-1-ones is described. These compounds are useful as anti-tubercular agents in warm blooded animals.
The present invention is directed to compounds of formula (I) which are M1 receptor positive allosteric modulators and that are useful in the treatment of diseases in which the M1 receptor is involved, such as Alzheimer's disease, schizophrenia, pain or sleep disorders. The invention is also directed to pharmaceutical compositions comprising the compounds, and to the use of the compounds and compositions in the treatment of diseases mediated by the M1 receptor.
benziodarone selectively binds to transthyretin in plasma. Here, we report the development of benziodaroneanalogues with enhancedpotency for selectivebinding to transthyretin in plasma compared to benziodarone. These analogues featured substituents of chlorine, bromine, iodine, a methyl group, or a trifluoromethyl group, at the 4-position of the benzofuran ring. X-ray crystal structure analysis revealed
