The elimination of lithium, magnesium and aluminium enolatea of isobutyrates of medium ring cyclanols occurs in a syn fashion. A set of experimental procedures is presented. This elimination seems to be restricted to strained systems. The stereo-chemistry has been determined on stereospecifically deuterated cyclooctanol isobutyrates. The primary isotope effect kH/k2 was 3.0 ± 0.1 and the secondary
中环环醇的异丁酸酯的锂,镁和铝烯醇盐的消除以同步方式发生。提出了一组实验程序。这种消除似乎仅限于紧张的系统。立体化学已经在立体特异性氘化的环辛醇异丁酸酯上确定。一级同位素效应k H / k 2为3.0±0.1,二级同位素效应为1.1。为此同步消除和相关消除建议使用名称“β'β消除”。
