The conformational population of Z and E isomers of the amide bond in N-acetyl oxazolidines is dictated by the electronic nature of the vicinal aryl ring. Experimental and theoretical data support a rationale based on a strong and stereodirecting charge–charge interaction that should be added to the arsenal of non-covalent interactions and whose influence can be more important than once thought.
N-乙酰基恶唑烷中酰胺键的 Z 和 E 异构体的构象群由邻芳环的电子性质决定。实验和理论数据支持基于强立体定向电荷-电荷相互作用的基本原理,这种相互作用应该被添加到非共价相互作用的库中,并且其影响可能比以前想象的更重要。
