4-Arylchroman-2-ones and 1-arylbenzo[f]chroman-3-ones can be prepared in moderate to good yields by reaction of phenols or β-naphthols with p-substituted methyl cinnamates in o-xylene under reflux.

Twelve 4-aryl-3,4-dihydrocoumarins were synthesized by the condensation of phenols with the corresponding substituted cinnamic acids in the presence of nitrobenzene and sulfated montmorillonite K-10. This method displayed the property of green chemistry with respect of reuse of the catalyst. These compounds were evaluated for hydroxyl radical scavenging activity in vitro. Results showed that compounds with 7,8-dihydroxy groups had relatively strong hydroxyl radical scavenging activity.

Alzheimer's disease (AD) is a progressive neurological degenerative disease that has complex pathogenesis. A variety of studies in humans indicate that several enzymes inhibitors can be useful in the treatment of AD, including acetylcholinesterase (AchE), butyrylcholinesterase (BuChE) and monoamine oxidase (MAO). Various substituted 4-arylcoumarin derivatives were synthesised, and their activity in vitro were investigated, including AChE/BuChE inhibitory activity, MAO inhibitory activity, and antioxidant activity. Most of the compounds were found to exhibit high inhibitory activity, and individual compounds have extremely excellent activities. Therefore 4-arylcoumarins provides an idea for drugs design for the development of therapeutic or preventive agents for AD.
