Pseudodimeric cyclobutanes constitute a large class of natural products that could, in principle, be efficiently synthesized via [2+2] photocycloadditions. However, the difficulty in developing chemo-, regio-, diastereo-, and enantioselective cycloadditions has limited their use in asymmetric syntheses. Herein, we show that chiral acid catalysts promote highly selective visible-light photocycloadditions
伪二聚环丁烷构成一大类天然产物,原则上可以通过[2+2]光环加成有效合成。然而,开发化学选择性、区域选择性、非对映选择性和对映选择性环加成的困难限制了它们在不对称合成中的应用。在此,我们证明手性酸催化剂促进高选择性可见光光环加成,其产物可以快速转化为truxinate天然产物。这种通用方法能够合成具有优异对映选择性的二聚体和假二聚体环丁烷天然产物。
