Saturated bicycles are becoming ever more important in the design and development of new pharmaceuticals. Here a new strategy for the synthesis of bicyclo[2.1.1]hexanes is described. These bicycles are significant because they have defined exit vectors, yet many substitution patterns are underexplored as building blocks. The process involves sensitization of a bicyclo[1.1.0]butane followed by cycloaddition
                                    饱和自行车在新药物的设计和开发中变得越来越重要。这里描述了一种合成
双环[2.1.1]己烷的新策略。这些自行车很重要,因为它们定义了退出向量,但许多替代模式作为构建块尚未得到充分探索。该过程涉及
双环[1.1.0]丁烷的敏化,然后与烯烃进行环加成。讨论了该方法的范围和机制细节。
