A Chemoenzymatic Synthesis of the Sex Pheromone of Lasioderma
A síntese quimioenzimática da forma enantiomericamente enriquecida (80% ee) da (-)-serricornina (1), feromônio sexual da praga do fumo Lasioderma serricorne F., foi alcançada em 8 etapas e 13% de rendimento total a partir de (R)-3-hidroxipentanoato de metila, obtido da redução de 3-oxopentanoato de metila com fermento de padaria (S. cerevisiae) na presença de álcool alílico como inibidor enzimá...
متن کاملEfficacy of Compounds Isolated from the Essential Oil of Artemisia lavandulaefolia in Control of the Cigarette Beetle, Lasioderma serricorne.
To develop natural product resources to control cigarette beetles (Lasioderma serricorne), the essential oil from Artemisia lavandulaefolia (Compositae) was investigated. Oil was extracted by hydrodistillation of the above-ground portion of A. lavandulaefolia and analyzed using gas chromatography-mass spectrometer (GC-MS). Extracted essential oil and three compounds isolated from the oil were t...
متن کاملDigestive proteinases in Lasioderma serricorne (Coleoptera: Anobiidae).
The cigarette beetle, Lasioderma serricorne (Fabricius), is a common pest of stored foods. A study of digestive proteinases in L. serricorne was performed to identify potential targets for proteinaceous biopesticides, such as proteinase inhibitors. Optimal casein hydrolysis by luminal proteinases of L. serricorne was in pH 8.5-9.0 buffers, although the pH of luminal contents was slightly acidic...
متن کامل2,4-Bis(4-fluorophenyl)-1,5-dimethyl-3-azabicyclo[3.3.1]nonan-9-one
The asymmetric unit of the title compound, C22H23F2NO, contains two independent mol-ecules, A and B. The bicyclic system adopts a twin-chair conformation in both mol-ecules. The dihedral angles between the fluoro-phenyl rings are 55.27 (8) and 56.37 (7)° in mol-ecules A and B, respectively. The NH groups are not involved in hydrogen bonding due to the steric hindrance of fluoro-phenyl groups. T...
متن کاملSYNTHESIS OF 8-HYDROXY-6-METHOXY- 3-UNDECYLISOCOUMARIN AND 2-HY DROXY - 4-METHOXY-6-(2-OXOTRIDECYL) BENZOIC ACID
Straightforward conversion of (+)-6,8-dimethoxy-3,4-dihydro-3- undecylisocoumarin (3) to the title isocoumarin was carried out. Hydrolytic ring opening of (3) afforded the hydroxy acid (4) which was immediately oxidized to keto acid (5) using chromic acid, Cyclodehydration of (5) afforded the 6,8- dimethoxy-3-undecylisocoumarin (6) which on selective demethylation of 8- methoxy group furni...
