Aspidoptoids A-D: Four New Diterpenoids from <i>Aspidopterys obcordata</i> Vine.
Molecules (Basel, Switzerland) 20200125 3
Four new diterpenoids, named aspidoptoids A-D (<b>1</b>-<b>4</b>), together with two known analogues (<b>5</b>-<b>6</b>) were isolated from <i>Aspidopterys obcordata</i> vine. Aspidoptoids A-B (<b>1</b>-<b>2</b>) are the first examples of phenylethylene-bearing 20-nor-diterpenoids of which aspidoptoid B (<b>2</b>) possesses a rare 3,10-oxybridge. Their structures and absolute configuration were determined by extensive spectroscopic analyses (IR, HRESIMS, 1D and 2D NMR) and electronic circular di ...[more]
