Applicazioni

trans-Cinnamic acid is used in flavors, synthetic indigo and pharmaceuticals. It is involved in the production of methyl, ethyl and benzyl esters, which is used in the perfume industry. It serves as a precursor to the sweetener aspartame through enzyme-catalyzed amination to phenylalanine. It is a self-inhibitor produced by fungal spores to prevent germination. In addition, it is used to establish phenolic compounds by liquid chromatography, ultraviolet and mass spectrometry. It is utilized as a potential agent, thereby preventing lung tumor cells from metastasizing. Further, it induces intracellular release of calcium ions from the vacuole to the cytoplasm in order to trigger phytotoxicity in cucumber.

Note

Incompatible with strong oxidizing agents.

Letteratura

Heating with excess thionyl chloride and a catalytic amount of pyridine gives a benzo[b]thiophene derivative, formed by electrophilic addition of thionyl chloride across the double bond of cinnamoyl chloride, Pummerer rearrangement of the resulting sulfinyl chloride and final cyclization. ɑ-Chlorocinnamoyl chloride is formed as a by-product by elimination of SCl2: J. Org. Chem., 40, 3037 (1975):

Under similar conditions, 3-phenylpropionic acid gave the same products in lower yield; the reaction was thought to occur via an initial ɑ-enolization of the acid chloride: Tetrahedron Lett., 5149 (1968).
