Cinnamic acid hydroxylase in spinach
Phytochemistry, 1965Abstract An acetone precipitate from an extract of spinach leaves catalysed the hydroxylation of trans-cinnamic acid to p-coumaric acid. The enzyme was unstable and could not be purified. Crude preparations had a pH optimum of 4–6 and showed an absolute requirement for an external electron donor. Tetrahydrofolic acid and a reduced pyridine nucleotide

Structure of a cinnamic acid derivative
Acta Crystallographica Section C Crystal Structure Communications, 1992C 26 H 29 NO 2 cristallise dans P2 1 2 1 2 1 avec a=9,777, b=10,211, c=22,585A, Z=4; affinement jusqu'a R=0,043. Le groupement isocyano est syn par rapport a l'atome O du carbonyl et cis par rapport au groupement phenyl. Ce phenyl forme un angle de rotation de 29° par rapport au plan du systeme conjugue π adjacent.

(η2-Cinnamic)tetracarbonyliron acids. synthesis and acidity
Journal of Organometallic Chemistry, 1977Abstract (η2-cinnamic)tetracarbonyliron acids [(η2-XC6H4CHCHCOOH) Fe(CO)4] (X = H, 3-OMe, 4-OMe, 4-Me, 3-Cl, 4-CI) have been prepared and their PKa's measured spectrophotometrically. The measured acidities indicate that the [Fe(CO)4] group is electron releasing.

High-yield synthesis of bioactive ethyl cinnamate by enzymatic esterification of cinnamic acid
Food Chemistry, 2016In this paper, Lipozyme TLIM-catalyzed synthesis of ethyl cinnamate through esterification of cinnamic acid with ethanol was studied. In order to increase the yield of ethyl cinnamate, several media, including acetone, isooctane, DMSO and solvent-free medium, were investigated in this reaction.
