Abstract
The stereochemistry of the steroidal alkaloid oblonginine from Veratru m oblongum (Chinese name Changgenglilu), previously reported to posses s the structure (22R,25S)-22,26-epiminocholest-5-en-3 beta-ol, was re- examined using X-ray crystallography and high resolution NMR spectrosc opy and reassigned with regard to C-22 and C-25. Therefore, oblonginin e has the structure (22S,25R)-22,26-epiminocholest-5-en-3 beta-ol. (C) 1998 Elsevier Science Ltd. All rights reserved.
