An efficient reaction utilizing propargyl carbonates through Claisen rearrangement to synthesize furanonaphthoquinones is described. The remarkable transformation exhibits excellent functional group tolerance, affording the target furanonaphthoquinones in moderate to good yields (41–85%) under mild reaction conditions. Scaled-up preparation of the model product can make this reaction a method of choice
描述了一种有效的反应,该反应利用碳酸炔丙酯通过克莱森重排来合成呋喃萘甲醌。出色的转化表现出出色的官能团耐受性,在温和的反应条件下,目标呋喃萘醌的收率中等至良好(41–85%)。扩大模型产品的制备可使该反应成为合成呋喃并萘醌衍生物的一种选择方法。在体外评价所得呋喃萘醌为潜在的吲哚胺2,3-二加氧酶抑制剂。
