Muñoz, Marcelo A.; Muñoz Muñoz, Orlando; Joseph-Nathan, Pedro (Wiley InterScience, 2010)The absolute configuration of semisynthetic (2)-3a,6b-acetoxytropane 1, prepared from (2)-6b-hydroxyhyoscyamine 2, has been determined using vibrational circular dichroism (VCD) spectroscopy. The vibrational spectra (IR ...

Areche Medina, Carlos; San Martín Barrientos, Aurelio; Rovirosa, Juana; Muñoz, Marcelo A.; Hernández Barragán, Angelina; Bucio, María A.; Joseph-Nathan, Pedro (2010)Careful examination of the published NMR data for isoepitaondiol, a meroditerpenoid from Stypopodium flabelliforme, suggests that its published structure 1 must be revised. On the basis of extensive 1D and 2D NMR studies, ...
