corresponding α,β,β-trifluorocyclopropane carboxylic acid. Reactions of the corresponding amides with phenol/thiophenol resulted in HF elimination and then conjugate addition. The partially fluorinated cyclopropane has a similar lipophilicity to –CF3 despite three carbon atoms, and it emerges as a novel motif for drug discovery.
报道了制备芳基α,β,β-三氟环丙烷的一般路线,芳基氧化得到相应的α,β,β-三氟环丙烷羧酸。相应的酰胺与苯酚/硫代苯酚的反应导致HF的消除,然后共轭物的添加。尽管有三个碳原子,部分氟化的环丙烷具有与–CF 3相似的亲脂性,并且它作为药物发现的新主题而出现。
