Resumen:
or a new steroidal lactol, jaborosalactol 24, isolated from Jaborosa parviflora, NMR spectroscopy residual dipolar couplings and powder X-ray diffraction analysis independently gave the same stereochemistry at C23-C26. Conventional NMR spectroscopic techniques, such as NOE and 3J coupling-constant analysis failed to unambiguously determine this stereochemistry.
