The title compound (FBDT), a cyclic analogue of 1‐fluorobis(phenylsulfonyl)methane (FBSM), was developed as a reagent for the nucleophilic monofluoromethylation of aldehydes. By choice of an appropriate base it is possible to achieve selective 1,2‐ or 1,4‐addition of FBDT to conjugated aldehydes. The method was applied to the synthesis of a fluorinated isostere of osmundalactone.
选择的物质:标题化合物(FBDT)是1-氟双(苯磺酰基)甲烷(FBSM)的环状类似物,被开发为醛类亲核单氟甲基化的试剂。通过选择合适的碱,可以实现将FBDT选择性地添加到共轭醛中1,2,或1,4-。该方法被应用于osmundalactone的氟化等排体的合成。
