Treatment of 3-[4-(2-bromophenyl)-2-phenylbutyryl]-4,4-dimethyloxazolidin-2-one with LDA in THF launched a domino rearrangement sequence ending in the assembly of a tetracyclic cyclopentaoxazolo[3,2-b]isoquinolin-6-one derivative. Two mechanisms involving an SRN1-type process were proposed. EPR spectroscopic and 13C-labelling experiments suggested that both were operative.(© Wiley-VCH Verlag GmbH &
在 THF 中用 LDA 处理 3-[4-(2-溴苯基)-2-苯基丁酰基]-4,4-二甲基恶唑烷-2-one 引发了多米诺重排序列,以四环环戊恶唑 [3,2-b 的组装结束]isoquinolin-6-one 衍生物。提出了两种涉及 SRN1 型过程的机制。EPR 光谱和 13C 标记实验表明两者都有效。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
