There is provided a labeling precursor compound represented by the following general formula (2):
wherein R1 represents an alkynyl group, an alkynyloxy group, an azide group, an azidoalkyl group, an arylazide group, a monocyclic or condensed polycyclic aryl group or a nitrogen-containing heterocycle; R2 and R3 each independently represent an alkyl group or a hydroxyalkyl group which hydroxy group may be protected with a protecting group, and n is an integer of 1 or 2; R6 represents an alkyl group or —CONR11R12 wherein R11 and R12 each independently represent an alkyl group or a monocyclic or condensed polycyclic aryl group; and R4, R5, R7 and R8 each independently represent a hydrogen atom, an alkyl group or an alkoxy group.
提供了一种由以下通式(2)表示的标记前体化合物:
其中 R1 代表炔基、炔氧基、叠氮基、叠氮烷基、芳基叠氮基、单环或缩合多环芳基或含氮杂环;R2 和 R3 各自独立地代表烷基或羟烷基,其中羟烷基可被保护基保护,且 n 为 1 或 2 的整数;R6代表烷基或-CONR11R12,其中 R11 和 R12 各自独立地代表烷基或单环或缩合多环芳基;以及 R4、R5、R7 和 R8 各自独立地代表氢原子、烷基或烷氧基。
