A convenient method for synthesizing elongated aliphatic esters from alkenes is reported. An (alkoxycarbonyl)methyl radical species is generated upon visible-light irradiation of an ester-stabilized phosphorus ylide in the presence of a photoredox catalyst. This radical species adds onto the carbon–carbon double bond of an alkene to produce an elongated aliphatic ester.

The excessive calpain activation causes serious cellular damage or even cell death in neurological disorders such as stroke and Alzheimer's disease. Oxidative stress has also been implicated in the initiation or progression of neurodegenerative diseases. In the present studies, a series of cinnamoyl ketoamides 4a-4j were synthesized as hybrid structures of antioxidants and calpain inhibitors. Cinnamoyl ketoamides, possessing an alkyl chain at the α-position, showed potent μ-calpain inhibitory activities indicating that the cinnamoyl skeleton can be regarded as an acyclic variant of calpain inhibitory chromone carboxamide 2. Among synthesized, compound 4e was the most potent inhibitor of μ-calpain (IC50 = 0.13 μM) and also exhibited strong antioxidant activities in DPPH and superoxide anion radical scavenging and lipid peroxidation inhibition assay systems.
