This study was designed to synthesize and evaluate flavanone derivatives with phenylcarbamate moiety as potent acetylcholinesterase (AChE) inhibitors and anti-amnestic agents for management of AD. The synthesis of carbamate-substituted flavanone derivatives involved base-catalysed Claisen-Schmidt condensation reaction of 2-hydroxy acetophenone/2-hydroxy-4,6-dimethoxyacetophenone with differently substituted
The selective and efficient oxidation of flavanones with dimethyldioxirane (DMD) is reported. Aromatic rings carrying methoxy groups were selectively hydroxylated in neutral and acidic media. In the latter case inversion of chemoselectivity with respect to the benzylethereal position was observed. This behaviour was exploited to obtain polyhydroxylated flavanones, which are compounds with potential antioxidant
