Multigram synthesis of 2- and 3-monofluorinated cyclobutane building blocks was disclosed. In both cases, fluorocyclobutanecarboxylic acids were the key intermediates used to obtain all other derivatives, e. g., amines, alcohols, bromides, thiols, sulfonyl chlorides, etc. For both target chemotypes, diastereopure cis- and trans-isomers of the corresponding carboxylic acids and amines were obtained
公开了2-和3-单氟化环丁烷结构单元的多克合成。在这两种情况下,氟环丁烷羧酸是用于获得所有其他衍生物(例如胺、醇、溴化物、硫醇、磺酰氯等)的关键中间体。对于这两种目标化学型,相应羧酸的非对映纯顺式和反式异构体以及通过非对映异构体分离得到胺。还通过模型衍生物的pKa和 Log P测量来表征2-和 3- 氟环丁基取代基。
