Biotransformation of (-)-(1R,4S)-Menthone and (+)-(1S,4R)-Menthone by the Common Cutworm Spodoptera litura Larvae.
Using biotransformation as a biocatalytic process has the advantage of being able to proceed under mild conditions and with high regio- and enantioselectivity. This study investigated the biotransformation of (-)-(1R,4S)-menthone (1) and (+)-(1S,4R)-menthone (2) by Spodoptera litura larvae. Compound 1 was converted to (-)-(1R,4S)-7-hydroxymenthone (1-1), (+)-(1R,3S,4S)-7-hydroxyneomenthol (1-2)...
متن کاملBiotransformation of sinesetin by the larvae of the common cutworm (Spodoptera litura).
Biotransformation of sinesetin (1) by larvae of Spodoptera litura was investigated. Compound 1 was converted to a new flavonoid, (+)-5,7,3',4'-tetramethoxyflavone-6-O-beta-D-glucoside (4), and two known flavones, 4'-hydroxy-5,6,7,3'-tetramethoxyflavone (2) and 6-hydroxy-5,7,3',4'-tetramethoxyflavone (3). These structures were established by IR, HR-EI-MS, HR-FAB-MS, 1D NMR, and 2D NMR spectral s...
متن کاملNew Liquid Crystalline Tolanes from (-)-Menthone
Synthetic manipulations were carried out with the aim of obtaining an advanced linear fragment for production of thermotropic liquid crystals. The chiral fragment synthesised was introduced in a tolanbenzoate mesogenic core by coupling of Sonogashira. The nal chiral tolans showed smectic A and C and nematic liquid crystalline phases. The crystallographic structure of lactone from (-) menthone i...
متن کاملSelective hydrogenation of menthone on Raney nickel catalyst
The present study deals with the selective hydrogenation of menthone to menthol in a Parr reactor. The reactions are carried out in the temperature range of 100-200°C, pressure range of 5-20 kg/cm, 100 mL solvent and catalyst to substrate ratio ranging from 0-10% for a reaction time of 4-5 h. The samples are then analyzed using a gas chromatograph for determining the conversion and then selecti...
متن کاملAllometric Ratio of Menthol and Menthone to Pulegone in the Essential Oil of Peppermint (Mentha piperita L.) Affected by Bioregulators
Background and objectives: Menthol and menthone are two important components in the essential oil of peppermint(Mentha piperita L.) which are commercially used in the pharmaceutical industries. This study has presented the allometric ratio of menthol and menthone to pulegone affected by the induction of bioregulators. Methods: The experiment w...
