of alkyl and benzyl halides using α-fluoro-α-(phenylsulfonyl)methane (1) as a highly versatile reagent is reported. Using benzyl halides, stereospecific one-pot synthesis of α-fluorovinyl compounds such as α-fluorostyrylsulfones, α-fluorocinnamates, and α-fluorochalcones has been achieved. The methodology has been extended toward the synthesis of α-substituted fluoroalkane derivatives using selective
报道了一种使用α-氟-α-(苯基磺酰基)甲烷(1)作为高度通用的试剂进行烷基和苄基卤的亲核氟甲基化的有效方法。使用苄基卤,已经实现了α-氟乙烯基化合物如α-氟苯乙烯基砜,α-氟肉桂酸酯和α-氟代查耳酮的立体定向一锅合成。该方法已经扩展到使用选择性还原性脱磺酰化条件合成α-取代的氟代烷烃衍生物的方法。
