(‒)-Encecanescin (1) has been isolated from the leaves of Eupatorium aschembornianum. Two conformers are present in the crystal structure as a result of molecular disorder. The structure of 1 was established by 1H- and 13C-NMR spectroscopy in CDCl3

From a 60% hydroalcoholic extract of the seeds of Annona purpurea, a novel cyclooctapeptide, cyclopurpuracin (1), or cyclo(-Pro1-Gly2-Phe3-ILe4-Gly5-Ser6-Pro7-Val8-), has been isolated. The structure of cyclopurpuracin (1) was determined by de novo s

In this work, Annona diversifolia seed oil (ADO) is evaluated for the first time as potential biodiesel feedstock. ADO was found to contain 21% oil (w/w) after extraction, and the low acid value of the oil was 0.666 mg KOH/g. Therefore, ADO was consi

In recent publications there has been considerable speculation about the possible role of a single water molecule in the catalysis of reactions between organic volatile compounds and OH radicals. In this work we reanalyze the effect of water in the a

A comparison between a tetramolecular mechanism (J. Org. Chem. 2007, 72, 3031) and our previously proposed mechanism has been performed. The results show that the tetramolecular mechanism is less favored in terms of Gibbs free energy, and therefore,

The mechanism of Baeyer–Villiger reaction with substituted peracids is analyzed by determining with semiempirical (AM1 and PM3) methods, the Mulliken charges, structures, energies, and the evolution of bond orders. A significant correlation was fou
