obtained irradiating aqueous solutions (5 × 10−5 M). For mechanistic purposes and products studies irradiation has also been carried out on concentrated solutions (1 × 10−3 M) in water/acetonitrile, acetonitrile, methanol, methanol/acetonitrile, in the presence and absence of oxygen. Photoproducts, isolated by chromatographic processes, have been identified by spectroscopic means. Photochemical cleavage

Convenient and efficient syntheses of 3-vinylphenyl ethyl (methyl) carbamate, one of potential metabolites from rivastigmine, has been developed. The overall yield is higher than 30 % and represents the first direct synthesis of this metabolite from rivastigmine.
Butyrylcholinesterase (BuChE) and neuroinflammation have recently emerged as promising therapeutic directions for Alzheimer’s disease (AD). Herein, we synthesised 19 novel pyranone-carbamate deriva...
