A photochemical approach to polysubstituted heterocycles using UV-induced alkene isomerization is described. The method allows for the synthesis of disubstituted furans and pyrroles under mild and neutral conditions and also provides access to a class of trisubstituted furans pertinent to natural-product synthesis. The method has broad functional-group tolerance and many richly decorated heterocycles
描述了使用紫外线诱导的烯烃异构化的多取代杂环的光化学方法。该方法允许在温和和中性条件下合成二取代的呋喃和吡咯,并且还提供了一类与天然产物合成有关的三取代的呋喃。该方法具有宽泛的官能团耐受性,并且制备了许多装饰丰富的杂环,这些杂环并入了在布朗斯台德和路易斯酸性条件下不稳定的官能团。
