A novel fluorous taggingâdetagging strategy has been developed featuring a fluorination as the detagging process; fluorous allylsilanes were prepared by cross-metathesis and subsequently subjected to electrophilic fluorodesilylation; Selectfluor was used as the detagging reagent; the resulting allylic fluorides were successfully purified by fluorous solid phase extraction.
我们开发了一种新颖的荧光标记-脱标记策略,其特点是将
氟化作为脱标记过程;通过交叉甲基化反应制备了荧光烯丙基
硅烷,随后进行了亲电
氟硅烷化反应;使用 Selectfluor 作为脱标记试剂;通过荧光固相萃取成功纯化了所得到的烯丙基
氟化物。
