摘要：

The preparation of some (–)-kaur-16-enes carrying A-ring functionality analogous to some of the gibberellins is described. Thus kaura-2,16- dienes, chosen as analogues of gibberellin A5, have been derived from the succinate (VII) and the kaurenol (VIII). The succinate has also provided a simple route to (–).kaur-16-ene-3 β,19-diol. Intramolecular opening of the 2 β,3 β-epoxy function by the 19-hydroxyl group provides the oxetane (XXIV) from which (–)-kaur-16-ene-2 α,19-diol has been prepared. © 1969, CSIRO.
