Studies were conducted to assess glacial acetic acid (GAA) with various host plant volatiles (HPVs) and the sex pheromone, (E,E)-8, 10-dodecadien-1-ol, of codling moth, Cydia pomonella (L), as lures in traps for tortricid pests that often co-occur in tree fruits in the western United States. In addition to codling moth, field trapping studies were conducted with oriental fruit moth, Grapholita ...

Conjugated linoleic acid l-menthyl ester was hydrolyzed in water by the lipase from Candida rugosa with the addition of an organic solvent. The degree of hydrolysis (yield) greatly improved when a tertiary alcohol, such as t-butyl alcohol, was added. However, the addition of a less polar solvent, such as hexane, decreased the degree of hydrolysis, and some water-miscible solvents, such as aceto...

The title compound, C(13)H(18)N(2)O(4), crystallizes as discrete mol-ecules associated as N-H⋯O hydrogen-bonded dimers disposed about a crystallographic inversion centre. The structure is the first solid-state structure for a 3-acetyl-pyridone without C-4 to C-6 substituents. The amide subsituent at C-3 is coplanar with the pyridone ring, while the tert-butyl ester group is orthogonal to the py...

This study presents antibacterial activity of several organic metabolites produced by a fish pathogen, Acinetobacter sp. strain An 2, from marine ecosystem of Goa. Cell extract demonstrated stronger inhibitory effects on Gram negative bacteria as compared to common antibiotics. GC-MS analysis of crude cell extract revealed presence of potential antimicrobials (butylated hydroxytoluene, phenol, ...

A general method for the N-arylation of amino acid esters with aryl triflates is described. Both α- and β-amino acid esters, including methyl, tert-butyl, and benzyl esters, are viable substrates. Reaction optimization was carried out by design of experiment (DOE) analysis using JMP software. The mild reaction conditions, which use t-BuBrettPhos Pd G3 or G4 precatalyst, result in minimal racemi...

THE TITLE COMPOUND [SYSTEMATIC NAME: (2S,5S,8R)-tert-butyl 8-(1,1,1,3,3,3-hexafluoropropan-2-yl)-12-hydroxy-5-isobutyl-2,6-dimethyl-4,7-dioxo-10-oxa-3,6,9-triazadodecanoate], C(21)H(36)F(6)N(3)O(6), is a tripeptide crystallizing in the chiral ortho-rhom-bic spacegroup P2(1)2(1)2(1). The absolute configuration (R) of the chiral center in the hexa-fluoro-valine unit is based on the known stereoch...

Four N-phenyl substituted carbazole oxime ester photoinitiators were synthesized and their structure-activity relationship systematically investigated. These have a broad absorption in the range of 300-400 nm tail extends above 400 nm. Under 405 LED light irradiation, esters undergo photodecarboxylation generate active free radicals to induce polymerization acrylates. The tert-butyl aldehyde-ox...
