The addition of (pentafluoroethyl)- and (heptafluoropropyl)lithium to various acyl derivatives was studied. Weinreb and morpholine amides led to polyfluoro ketones in high to quantitative yields in short reaction times. Derivatives of 2-fluorocarboxylic acids may produce 1,1,1,2,2,4-hexafluoro ketones and 1,1,1,2,2,3,3,5-octafluoro ketones. The methodology can provide inhibitors for various lipolytic
研究了向各种酰基衍生物中添加(五氟乙基)-和(七氟丙基)锂。Weinreb和吗啉酰胺可在短反应时间内以高产率到定量产率产生多氟酮。2-氟羧酸的衍生物可产生1,1,1,2,2,4-六氟酮和1,1,1,2,2,3,3,5-八氟酮。该方法可以为各种脂解酶(包括磷脂酶A2)提供抑制剂。
