Ring the changes: A new photoassisted approach to give conformationally constrained N,O,S‐polyheterocyclic scaffolds of unprecedented topologies was achieved by intramolecular [4+4] and [4+2] cycloadditions of photogenerated o‐azaxylylenes (23 examples; see scheme). The precursors can be readily assembled by simple and high‐yielding reactions, thus making this a powerful synthetic method amenable to
改变变化:通过光生邻氮杂二甲苯的分子内 [4+4] 和 [4+2] 环加成实现了一种新的光辅助方法,可提供具有前所未有拓扑结构的构象受限的 N、O、S-多杂环支架(23 个示例;参见方案) )。前体可以通过简单和高产率的反应轻松组装,从而使其成为一种强大的合成方法,适用于高通量的多样性导向合成。
