Conformational Behavior and Epoxidation of the Dolabella-3E,7E-dienoid
摘要:
Conformational analysis of the dolabellane diterpenoid, 6β-acetoxy-12β-hydroxydolabella-3E,7E-diene containing 1,5-undecadiene, has been achieved by means of molecular mechanics calculations, 1H NMR, and CD spectrometry. The epoxidation products of the diene can be rationalized in terms of the calculated equilibrium conformations.

Abstract Five new dolabellanediterpenoids have been isolated from the liverwortOdontoschismadenudatum, and their structures and absolute configurations have been determined on the basis of 1H and 13C NMR evidence and chemical correlation.
