通过芳香酰氯, 丙烯酸酰氯或二甲基氯化膦与中间物(标题化合物)的原位反应, 合成了十一个混合配位桥联的六羰基二铁配合物, 它们的结构皆经元素分析, IR和'HNMR证实, 对于含二甲膦系列的配合物, 还测得3'PNMR谱, 并根据其'H及31PNHR数据进一步推断出这类配合物所具有的可能构象。

The first chemoselective transformations of oridonin (I) to eriocalyxin B (II), dehydroeriocalyxin A (III) and their analogs-14-hydroxyeriocalyxin B (IV) and 14-hydroxydehydroeriocalyxin A (V) are described. The overall yield of II and III from I is 11 and 10% in six and seven steps, resp. The overall yield of IV and V from I is 57 and 49% in four and five steps, resp.
