Cinnamaldehyde is an organic compound with the formula C 9 H 8 O or C 6 H 6 CH=CHCHO. Occurring naturally as predominantly the trans ( E ) isomer, it gives cinnamon its flavor and odor . [ 1 ] It is a phenylpropanoid that is naturally synthesized by the shikimate pathway . [ 2 ]
cinnamyl alcohol + NADP + cinnamaldehyde + NADPH + H + Thus, the two substrates of this enzyme are cinnamyl alcohol and NADP + , whereas its 3 products are cinnamaldehyde , NADPH , and H + . This enzyme belongs to the family of oxidoreductases , specifically those acting on the CH-OH group of donor with NAD + or NADP + as acceptor.

Cinnamoyl-CoA reductase (EC 1.2.1.44), systematically named cinnamaldehyde:NADP+ oxidoreductase (CoA-cinnamoylating) but commonly referred to by the acronym CCR, is an enzyme that catalyzes the reduction of a substituted cinnamoyl-CoA to its corresponding cinnamaldehyde, utilizing NADPH and H + and releasing free CoA and NADP + in the process.

The European Parliament registered cinnamyl acetate as both a flavouring substance and a cosmetic compound in 1996. [14] [15] The Joint (FAO/WHO) Expert Committee on Food Additives described in 2000 that “the substance does not present a safety concern at current levels of intake when used as a flavouring agent”.

Nitration of cinnamaldehyde via acidification of a nitrate salt with H 2 SO 4 also yields the ortho-nitro compound, however it also yields some of the para-nitro compound, which is generally undesired. 2-Nitrocinnamaldehyde can also be prepared by reacting 2-nitrobenzaldehyde with acetaldehyde in a condensation reaction.
