双黄酮是黄酮类化合物中较为复杂的一类化合物，它们大多为药用植物（特别是中草药）的有效成分。我们实验室以合成狼毒素（ｃｈａｍａｅｊａｓｍｉｎｅ）［１］为目标，对Ｃ３－３双黄酮的合成做了一些研究，利用３－位锂化碘代黄酮的方法，［２，３］成功地合成了几个Ｃ－３?
Biflavonoids are a more complex class of flavonoids, most of which are active ingredients of medicinal plants, especially Chinese herbal medicines. Our lab has done some research on the synthesis of C3-3 bflavone with the goal of synthesizing chamaejasmine [1]. The 3-position lithiodiodoflavone method [2,3] was successfully used to synthesize How many C-3?
