The origins of the boat transition state preference in the Ireland-Claisen rearrangements studied experimentally by Kishi and co-workers have been explored computationally with Density Functional Theory. Steric interactions in the chair transition states were identified as the principal reason for the boat transition state preference.
基希(Kishi)及其同事通过实验研究爱尔兰-克莱森(Ireland-Claisen)重排反应中过渡态的构象偏好,并用密度泛函理论进行了计算研究。在椅式过渡态中,立体相互作用被确定为构象偏好的主要原因。
