A systematic study of the addition of C‐based nucleophiles to fluorinated lactones based on 2‐deoxy‐2‐fluoro‐d‐pyranoses is disclosed. This high yielding, α‐selective process was found to be independent on the nature or configuration [(R)‐C(sp3)–F, (S)‐C(sp3)–F] of the substituent at C2. Representative, fluorinated analogues of Trehalose, Carminic acid, and the spirocyclic cores of Tofogliflozin and
公开了将基于 C 的亲核试剂添加到基于 2-脱氧-2-氟-d-吡喃糖的氟化内酯的系统研究。发现这种高产率的 α 选择性过程与 C2 处取代基的性质或构型 [(R)-C(sp3)-F, (S)-C(sp3)-F] 无关。还报道了海藻糖、胭脂红酸的代表性氟化类似物以及 Tofogliflozin 和 Papulacandin D 的螺环核心。这些糖模拟物构成了一系列有价值的 19F NMR 活性探针,可用于结构生物学。

Synthesis of Fluorinated Ketoheptoses as Specific Diagnostic Agents
The straightforward syntheses of six regioisomeric mono- and difluorinated D-manno-heptulose and Kamusol analogues, which use electrophilic or nucleophilic fluorinaton, are reported. D-manno-Heptulose shows attractive pharmacological properties in vivo, such as antitumour activity, as well as binding to and accumulating in pancreatic beta cells to induce hyperglycemia. The synthesised analogues represent
