functional theory calculations were applied to predict the pathways of gold(I)-catalyzed cycloisomerization of the indole substrates with 1,6-enynes, which were consistent with the ensuing experimental results. The substitution-controlled synthesis led to the formation of 1H-pyrido[4,3-b]indole and spiro[indoline-3,3′-pyridine] derivatives in a tunable way. The reactions had good functional group tolerances
应用密度泛函理论计算预测了金(I)催化的吲哚底物与 1,6-烯炔的环化异构化途径,这与随后的实验结果一致。取代控制合成导致以可调方式形成 1 H-吡啶并[4,3- b ]吲哚和螺[吲哚啉-3,3'-吡啶]衍生物。该反应具有良好的官能团耐受性,并根据计算和实验结果提出了可能的机理。
