deoxofluorination of β-keto esters using SF4 was investigated. The scope and limitation of the reaction were determined. The efficient method for the synthesis of β,β-difluorocarboxylic acids was elaborated based on the reaction. The set of mentioned acids, being the perspective building blocks for medicinal chemistry, were synthesized on multigram scale. The safety of SF4 use was discussed. The described

Fearless Fluorine: the effect of gem-diflurination on acidity/basicity (pKa), lipophilicity (LogP), aqueous solubility (Sw), and metabolic stability (intrinsic clearance, CLint) of functionalized C3−C7-cycloalkanes is established and compared to those of non-fluorinated and acyclic counterparts. While the pKa values are varied similarly for the cyclic and acyclic series and can be explained by the
Fearless Fluorine:gem -diflurination 对官能化 C 3 -C 7 -环烷烃的酸度/碱度 (pK a )、亲油性 (Log P )、水溶性 ( S w ) 和代谢稳定性(固有清除率,CL int )的影响建立并与非氟化和无环对应物进行比较。虽然循环和非循环系列的 p K a值变化相似,并且可以通过氟原子的感应效应来解释,但 Log P和S w趋势更复杂。CL整数宝石二氟化后的值保持不变或略有改善。
