The first use of the spirodiepoxide functional group in total synthesis, a study culminating in an efficient synthesis of the potent proteasome inhibitor epoxomicin, is described. Spirodiepoxides derived from allenes by oxidation are shown to give syn disubstituted ketones and their derivatives, including ortho ester, oxazoline, azido epoxide, as well as sulfonamide-, amide-, and azide-containing hydroxy
描述了螺二环氧化物官能团在全合成中的首次使用,该研究最终以有效合成有效的蛋白酶体抑制剂环氧霉素为高潮。通过氧化从丙二烯衍生的螺二环氧化物显示出顺式双取代酮及其衍生物,包括原酸酯、恶唑啉、叠氮环氧化物以及含磺酰胺、酰胺和叠氮化物的羟基酮。
