A variety of substituted isocampholenic acid derivatives were prepared by rearrangement of the camphor skeleton of a variety of tertiary alcohols derived from ketopinic acid. The reaction was highly reliable and retained the stereochemical information from the camphor scaffold. This rearrangement represents an efficient way to prepare synthetically useful isocampholenic acids. Mechanistic experiments
通过重排衍生自酮多酸的各种叔醇的樟脑骨架,制备了各种取代的异樟脑酸衍生物。该反应是高度可靠的,并且保留了来自樟脑支架的立体化学信息。这种重排代表了制备合成上有用的异马来酸的有效方法。机理实验表明,该反应涉及短寿命的碳正离子化。
