Seven-membered cyclic α-monofluorophosphonate esters such as 2-allyloxy-3-fluoro-3-phenylthio-4,7-dihydro-[1, 2]-oxaphosphinine-2-oxide were successfully synthesized in moderate total yield as 41% from open-chain allyl phosphonates having an α-arylthio group as an electroauxiliary using an alternative sequence of anodic fluorination and ring-closing olefin metathesis (RCM). On the other hand, in an
七元环状α-单氟膦酸酯,如2-烯丙氧基-3-氟-3-苯硫基-4,7-二氢-[1,2]-氧代膦-2-氧化物已成功合成,得自41%使用阳极氟化和闭环烯烃复分解(RCM)的替代序列,将具有α-芳硫基基团的开链烯丙基膦酸酯用作电助剂。另一方面,为了合成八元类似物,主要通过烯丙氧基之间的RCM反应形成了不同类型的七元氟化环状产物。
