modification of the classical preparation of phenanthrenes by UV irradiation of stilbenes in the presence of an oxidant. This modification involves the irradiation, in the presence of base, of stilbenes possessing a sulfonyl group linked to the central double bond. We have proved that this protocol can be successfully applied for the synthesis of diverse phenanthrenes and phenanthrenoids.
我们已经通过在氧化剂存在下紫外线照射对苯二酚对菲的经典制备方法进行了有用的修饰。该修饰涉及在碱的存在下辐照具有连接至中心双键的磺酰基的丁二烯。我们已经证明,该协议可以成功地应用于各种菲和菲类化合物的合成。
