一个溶剂依赖性的立体选择性分子内[4 + 4]光环加成的栓系2-吡啶酮是浓度依赖性，表明具有四个氢键的二聚体结构中起着关键作用，在观察到的顺式选择性的非极性溶剂。
A solvent-dependent stereoselectivity found for intramolecular [4 + 4] photocycloaddition of tethered 2-pyridones is concentration dependent, indicating that a dimeric structure with four hydrogen bonds plays a critical role in the observed cis selectivity found for nonpolar solvents.
