Beschreibung
(+)-Menthol is a monoterpene alcohol that has been found in Cannabis and has antifungal activity. It inhibits the growth of F. verticillioides (MIC = 1.5 mM). Unlike (–)-menthol, (+)-menthol does not exhibit analgesia, antibacterial, anticancer, or cholinesterase inhibitory activities.
Chemische Eigenschaften
(+)-MENTHOL is white low melting solid
Verwenden
(+)-MENTHOL is used for oral gel patch or film containing herb extracts or Chinese medicine, fruit extract, spearmint, and menthol for smoking cessation.
Verwenden
(1S,2R,5S)-(+)-menthol can undergo acylation with acid anhydrides in the presence of trimethylsilyl trifluoromethanesulfonate to form the corresponding acylated products.
Definition
ChEBI: (+)-menthol is a p-menthan-3-ol which has (1S,2R,5S)-stereochemistry. In contrast to (-)-menthol, the (+)-enantiomer occurs only rarely in nature. It is an enantiomer of a (-)-menthol.
Allgemeine Beschreibung
(1S,2R,5S)-(+)-menthol is a chiral secondary alcohol. Its alcohol group can be protected as 2-tetrahydrofuranyl ether by reacting with bromotrichloromethane and tetrahydrofuran.
Synthese
Prod.: by Meerwein-Ponndorf-Verley reduction of l-Menthone, resuhing in approximately two-thirds d-Neomenthol plus one-third i-Menthol. It can also be produced by reduction of d-Menthone.
