A new method for the preparation of derivatives of furocoumarin natural products is described. The 6(8)-(1,2,3-thiadiazol-4-yl)-7-hydroxycoumarins smoothly transform into 2-alkylthio angelicin and psoralen derivatives through base catalyzed thiadiazole ring cleavage and subsequent furan ring closure.
介绍了一种制备呋喃香豆素天然产物衍生物的新方法。 6(8)-(1,2,3-噻二唑-4-基)-7-羟基香豆素通过碱催化噻二唑环裂解和随后的呋喃环闭合顺利转化为2-烷硫基当归素和补骨脂素衍生物。
