Menthol may also enhance the activity of glycine receptors and negatively modulate 5-HT 3 receptors and nAChRs. [9] Menthol is widely used in dental care as a topical antibacterial agent, effective against several types of streptococci and lactobacilli. [10] Menthol also lowers blood pressure and antagonizes vasoconstriction through TRPM8 ...
Menthone was first synthesized by oxidation of menthol in 1881, [6] [needs update] [7] before being found as a component in essential oils in 1891. [ citation needed ] Of the isomers possible for this chemical structure (see below), the one termed l -menthone —formally, the (2 S ,5 R )- trans -2-isopropyl-5-methylcyclohexanone (see infobox ...
In stereochemistry, a chiral auxiliary is a stereogenic group or unit that is temporarily incorporated into an organic compound in order to control the stereochemical outcome of the synthesis. [1] [2] The chirality present in the auxiliary can bias the stereoselectivity of one or more subsequent reactions. The auxiliary can then be typically ...
p-Menthane-3,8-diol, also known as para-menthane-3,8-diol, PMD, or menthoglycol, is an organic compound classified as a diol and a terpenoid.It is colorless. Its name reflects the hydrocarbon backbone, which is that of p-menthane.
The Rothemund reaction is a condensation/oxidation process that converts four pyrroles and four aldehydes into a porphyrin. It is based on work by Paul Rothemund, who first reported it in 1936. [1] The method underpins more modern synthesis such as those described by Adler and Longo and by Lindsey.
The importance of this observation was that, in theory, if a half equivalent of (−)-menthol had been used, a highly enantioenriched sample of (−)-mandelic acid could have been prepared. This observation led to the successful kinetic resolution of other chiral acids, the beginning of the use of kinetic resolution in organic chemistry.
Organic synthesis is an important chemical process that is integral to many scientific fields. Examples of fields beyond chemistry that require organic synthesis include the medical industry, pharmaceutical industry, and many more. Organic processes allow for the industrial-scale creation of pharmaceutical products.
