The rearrangement of dihydropyrans and dihydrofurans featuring appending olefins has been studied. The rearranged products bear resemblance with polyunsaturated di- and trisaccharides. Examples of functionalization prior to, or following, rearrangement are provided suggesting that the method should be useful for the synthesis of nonclassical saccharides. This work also illustrates the power of cascade
已经研究了以附加烯烃为特征的二氢吡喃和二氢呋喃的重排。重排产物与多不饱和二糖和三糖相似。提供了在重排之前或之后的官能化的实例,表明该方法应可用于合成非经典糖类。这项工作还说明了级联介观过程从相对简单的杂环开始增加分子复杂性的能力。
