In one aspect, the present invention provides a method for labeling a terminal olefin, the method comprising a step of treating a terminal olefin substrate having the structure:
with a labeled ethylene reagent in the presence of a suitable catalyst under suitable olefin metathesis reaction conditions to form a labeled terminal olefin having the structure:
wherein R
A
and R
B
are independently hydrogen, or an aliphatic, alicyclic, heteroaliphatic, heterocyclic, aryl or heteroaryl moiety, with the proviso that R
A
and R
B
are not each hydrogen, or R
A
and R
B
taken together with the carbon atom to which they are attached form an alicyclic or heterocyclic moiety; and * denotes the presence of an isotopic label on the terminal carbon atom.
一方面,本发明提供了一种标记末端烯烃的方法,该方法包括以下步骤:在合适的烯烃偏析反应条件下,在合适的催化剂存在下,用标记乙烯试剂处理具有以下结构的末端烯烃底物,以形成具有以下结构的标记末端烯烃:
在合适的烯烃偏析反应条件下,在合适的催化剂存在下,用标记乙烯试剂处理具有以下结构的末端烯烃,以形成具有以下结构的标记末端烯烃:
其中 R
A
和 R
B
独立地为氢、脂肪族、脂环族、杂脂环族、杂环族、芳基或杂芳基,但 R
A
和 R
B
并非都是氢,或 R
A
和 R
B
与它们所连接的碳原子一起形成脂环族或杂环族分子;* 表示末端碳原子上存在同位素标记。
