In Silico Reassignment of (+)-Diplopyrone by NMR Calculations: Use of a DP4/ J-DP4/DP4+/DIP Tandem to Revise Both Relative and Absolute Configuration
(American Chemical Society, 2020-09)
The structural revision of natural (+)-diplopyrone (ND) was achieved by quantum NMR calculations. A DP4/J-DP4/DP4+ tandem suggested 3 as the most likely structure, but ECD calculations did not match the experimental values. ...
Structure and absolute configuration of a secolignan from Peperomia blanda
(Elsevier B.V., 2011-09-01)
A secolignan, (-)-2-methyl-3-[bis(3 ',4 '-methylenedioxy-5 '-methoxyphenyl) methyl] butyrolactone (1), with a rare cis configuration was isolated from the aerial parts of Peperomia blanda (Piperaceae). The structure of ...
Albendazole sulfoxide enantiomers: Preparative chiral separation and absolute stereochemistry
(Elsevier B.V., 2012-03-23)
The enantiomeric separation of albendazole sulfoxide was carried out by simulated moving bed chromatography with variable zones (VARICOL). An overall recovery of 97% was achieved and enantiomeric ratios of 99.5% for raffinate ...

Entre la naturaleza y la dignidad: reflexiones sobre el fundamento de los derechos humanos
(Universidad de La SabanaDirección de publicaciones, 1998)
Sé que proponer hoy una nueva reflexión sobre el fundamento de los derechos humanos parecería una cuestión innecesaria, porqué podría decirse, como ya lo reconoció Bobbio desde 1964, este problema esta resuelto.
