Treatment of pyrrolidinone 3a with CAN under the usual conditions leads to formation of spiro compound 12, rather than to N-demethoxyphenylation. A study of the reactions of compound 12 with sodium chloride and sodium iodide furnished the proof for our assumption that the related non-isolable compounds 6 and 11 are the intermediates of the anomalous reactions of compounds 1a and 2a, respectively, with
在通常条件下用CAN处理吡咯烷酮3a导致形成螺环化合物12,而不是导致N-脱甲氧基苯基化。对化合物12与氯化钠和碘化钠反应的研究为我们的假设提供了证据,即相关的不可分离的化合物6和11分别是化合物1a和2a与CAN异常反应的中间产物。
