An approach to the preparation of gem-difluorocyclopentane/hexane-derived carboxylic acids and amines is described. Whereas for 3,3-difluoro-substituted cycloalkanones, straightforward deoxofluorination of the corresponding ketoesters led to the target compounds, in the case of 2,2-difluoro isomers, the bypass or alternative routes were necessary.
描述了制备宝石-二氟环戊烷/己烷衍生的羧酸和胺的方法。而对于3,3-二氟取代的环烷酮,相应的酮酯的直接脱氧氟化反应会生成目标化合物,而对于2,2-二氟异构体,则需要旁路或替代途径。
