Antioxidant activity of some ascorbic and cinnamic acids derivatives
Il Farmaco, 1998Some 4-benzoyl 3-hydroxy furan-2 (5H) ones (3a-d) and 2-amino 3-hydroxymethyl 4-aryl 4-oxo 2-butenoic acids (4a-h) have been synthesized. Compound 3c with an isobutyl substituent in the 5-position of the furan ring was the most effective (IC50 = 8.69 x 10(-4) M) in scavenging the superoxide anion.

Hydroformylation of cinnamic acid derivatives catalysed by rhodium complexes
Journal of Organometallic Chemistry, 1993Abstract The hydroformylation of methyl cinnamate catalysed by various rhodium complexes affords the aldehyde 1a with good chemo- and regio-selectivity, while in the case of methyl p-chlorocinnamate the predominant reaction is the substrate hydrogenation.

Reduction of ferrylmyoglobin by dietary phenolic acid derivatives of cinnamic acid
Free Radical Biology and Medicine, 1995The reaction of dietary phenolic acid derivatives of cinnamic acid with high valence states of horse myoglobin was studied. When metmyoglobin was oxidized by hydrogen peroxide (H2O2) in the presence of the phenolic acids, ferrylmyoglobin was reduced to metmyoglobin.

Cinnamic acid derivatives as inhibitors for chorismatases and isochorismatases
Bioorganic & Medicinal Chemistry Letters, 2013Chorismatases and isochorismatases catalyse the hydrolysis of chorismate or isochorismate leading to unsaturated cyclohexenoic acid derivatives. Based on simplification of the physiological substrates, two cinnamic acid-derived compounds, differing in the saturation of the side chain, were developed.

Chiral 2-phenyl succinic ester derivatives have been obtained under mild conditions, in short times and with satisfactory yields by electrochemical reduction of chiral cinnamic acid derivatives under a CO2 atmosphere. When 4R-(diphenylmethyl)-oxazolidin-2-one was used as a chiral auxiliary the two diastereoisomers could be easily separated by flash ...
