described flexible approaches to protoilludane‐like (5,6,4‐tricyclic ring) and marasmane‐like (5,6,3‐tricyclic ring) skeletons with naturally occurring cis/anti/cis stereochemistry using photochemical rearrangement of bicyclo[2.2.2]octenones and Diels‐Alder reaction of masked o‐benzoquinones as the key steps.
在这项工作中,我们描述了使用原位顺式/反式/顺式立体
化学方法通过自然
化学方法对原芥子烷样(5,6,4-
三环)和马拉曼尼样(5,6,3-
三环)骨架进行灵活处理的方法。双环[2.2.2]
辛烯酮和被掩盖的邻苯并醌的狄尔斯-阿尔德反应是关键步骤。
