6-benzomcomarin substituted pyrimidine derivatives 11–15 and 22–25 were synthesized, aiming to develop new imaging fluorescent agents. Analogously, treatment of 4-chloropyrimidine analog 16 with coumarin 3-carbohyrazide 5 under MWI condition followed by boiling with NH4OAc in HOAc furnished coumarin-1,2,4-triazolo-pyrimidine analog 18. The fluorescence property was investigated spectrophotometrically in
合成了一系列香豆素和5,6-苯并甲基豆香素取代的嘧啶衍生物11 – 15和22 – 25,旨在开发新的成像荧光剂。类似地,在MWI条件下用香豆素3-碳酰肼5处理4-氯嘧啶类似物16,然后用NH 4 OAc在HOAc中沸腾,得到香豆素-1,2,4-三唑并嘧啶类似物18。以罗丹明6G为标准染料,在MeOH中用分光光度法研究了荧光性质。所有化合物均在331至495 nm之间显示出发射。所有化合物的量子产率被发现是弱,除了甲基苯并香豆素-3-羧酸乙酯22其显示(Φ ˚F 相比罗丹明6G作为标准(Φ= 0.98)˚F = 0.95)。 香豆素和苯并香豆素衍生物共轭嘧啶支架的合成及其荧光性质,用于生物成像应用。纳吉·A·马苏迪(Najim A.
