Phenylpropanoic acid or hydrocinnamic acid is a carboxylic acid with the formula C 9 H 10 O 2 belonging to the class of phenylpropanoids. It is a white, crystalline solid with a sweet, floral scent at room temperature. Phenylpropanoic acid has a wide variety of uses including cosmetics, food additives, and pharmaceuticals. [5]
In chemistry, the hydrogenation of carbon–nitrogen double bonds is the addition of the elements of dihydrogen (H 2) across a carbon–nitrogen double bond, forming amines or amine derivatives. [1] Although a variety of general methods have been developed for the enantioselective hydrogenation of ketones, [ 2 ] methods for the hydrogenation of ...
Phenylpropanoic acid Index of chemical compounds with the same molecular formula This set index page lists chemical structure articles associated with the same molecular formula .
Chromic acid oxidizes it to benzoic acid; zinc and acetic acid reduce it to cinnamic acid, C 6 H 5 CH=CHCO 2 H, whilst sodium amalgam reduces it to hydrocinnamic acid, C 6 H 5 CH 2 CH 2 CO 2 H. Ortho-nitrophenylpropiolic acid, NO 2 C 6 H 4 CCCO 2 H, prepared by the action of alcoholic potash on ortho-nitrocinnamic acid dibromide, crystallizes ...
Hydroxylation of cinnamic acid in the 4-position by trans-cinnamate 4-monooxygenase leads to p-coumaric acid, which can be further modified into hydroxylated derivatives such as umbelliferone. Another use of p -coumaric acid via its thioester with coenzyme A , i.e. 4-coumaroyl-CoA , is the production of chalcones .
Ionic hydrogenation refers to hydrogenation achieved by the addition of a hydride to substrate that has been activated by an electrophile. Some ionic hydrogenations entail addition of H 2 to the substrate and some entail replacement of a heteroatom with hydride. [1] Traditionally, the method was developed for acid-induced reductions with ...
It is a common method to make amines and is widely used in green chemistry since it can be done catalytically in one-pot under mild conditions. In biochemistry, dehydrogenase enzymes use reductive amination to produce the amino acid glutamate. Additionally, there is ongoing research on alternative synthesis mechanisms with various metal ...
Phenylacetic, 3-phenylpropanoic and 3-phenylpropenoic acids are found in propolis, mammalian exocrine secretions or plant fragrances. During a systematic study of the lipids from seeds of the plant Araceae, [1] the presence of 13-phenyltridecanoic acid as a major component (5-16% of total fatty acids)was discovered. Other similar compounds but ...
