(PET) activation of silyl enol ethers for the synthesis of tricyclic hydrocarbons. The mechanism of this reaction was investigated by conducting independent radical-induced cyclizations of corresponding iodo ketones and performing density functional theory (DFT) calculations on the possible intermediates. Our aim was to explain the nature of the reactive intermediate of the cyclization step and to find
我们已使用甲硅烷基烯醇醚的光诱导电子转移 (PET) 活化来合成三环烃。通过对相应的碘酮进行独立的自由基诱导环化并对可能的中间体进行密度泛函理论 (DFT) 计算,研究了该反应的机理。我们的目的是解释环化步骤反应中间体的性质,并找出在该过程中观察到的各种选择性的原因。(C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004。
