DEL RIO, Rosa E. et al. Conformational and Configurational Analysis of (2R,3S,5R)-2,5-Dimethyltetrahydropyran-3-Carboxylic Acid. J. Mex. Chem. Soc [online]. 2006, vol.50, n.3, pp.119-125. ISSN 1870-249X.

The present work describes the conformational and configurational analysis of 2,5-dimethyltetrahydropyran-3-carboxylic acid using the ALTONA software developed by the group of Joseph-Nathan. The pyrancarboxylic acid was prepared from 23-ethylidene-diosgenin acetate by a sequence of reactions that involve acid catalyzed cleavage of the side chain of the sapogenin.

Keywords : NMR; sapogenins; ALTONA software; conformational analysis; configurational analysis.
