[EN] SUBSTITUTED THIADIAZOLYL DERIVATIVES AS DNA POLYMERASE THETA INHIBITORS [FR] DÉRIVÉS SUBSTITUÉS DE THIADIAZOLYLE COMME INHIBITEURS DE L'ADN POLYMÉRASE THÊTA
开发了一种有效的合成先前无法获得的2-取代的二氟环丁烷结构单元的方法,并已应用于多克规模。合成序列的关键步骤包括O保护的2-(羟甲基)环丁酮的脱氧氟化作用。测量了2,2-二氟环丁烷胺和2,2-二氟环丁烷羧酸或其衍生物的解离常数(p K a)和log P值,并将其与相应的3,3-二氟环丁烷衍生物和非氟化对应物所获得的值进行比较。使用X射线晶体学数据的出口向量图分析比较了2,2-和3,3-二氟环丁胺的三维结构。

The protocol proceeds via a Wagner–Meerwein rearrangement with mild reaction conditions, good functional group tolerance, and moderate to good yields. The product could be readily transformed to gem-difluorocyclobutane-containing carboxylic acid, amine, and alcohol, all of which are usefulbuildingblocks for biologically active molecule synthesis.
