Cinnamic acid is an organic compound with the formula C 6 H 5-CH=CH-COOH. It is a white crystalline compound that is slightly soluble in water, and freely soluble in many organic solvents. [ 4 ] Classified as an unsaturated carboxylic acid , it occurs naturally in a number of plants.
The major route, however, is the conversion of cinnamaldehyde into cinnamic acid by the enzyme aldehyde dehydrogenase. Next, the cinnamic acid is transformed into cinnamoyl CoA which is again converted to either cinnamoylglycine by N-acyl transferase or to benzoyl CoA through β-oxidation, the latter being the major
Methyl cinnamate is the methyl ester of cinnamic acid and is a white or transparent solid with a strong, aromatic odor. It is found naturally in a variety of plants, including in fruits, like strawberry, and some culinary spices, such as Sichuan pepper and some varieties of basil. [4]

Ethyl cinnamate is the ester of cinnamic acid and ethanol. It is present in the essential oil of cinnamon. [citation needed] Pure ethyl cinnamate has a "fruity and balsamic odor, reminiscent of cinnamon with an amber note". [1] The p-methoxy derivative is reported to be a monoamine oxidase inhibitor. [2]
PAL gives rise to trans-cinnamic acid. In the second step, 4-coumarate–CoA ligase (4CL) converts cinnamic acid to cinnamoyl-CoA by an acid–thiol ligation. [8] 4CL uses ATP to catalyze the formation of cinnamoyl-CoA. [11] 4CL effects this reaction in two steps.
Green chemistry, similar to sustainable chemistry or circular chemistry, [1] is an area of chemistry and chemical engineering focused on the design of products and processes that minimize or eliminate the use and generation of hazardous substances. [2]
The Perkin reaction is an organic reaction developed by English chemist William Henry Perkin in 1868 that is used to make cinnamic acids.It gives an α,β-unsaturated aromatic acid or α-substituted β-aryl acrylic acid by the aldol condensation of an aromatic aldehyde and an acid anhydride, in the presence of an alkali salt of the acid.
