  CsF-Catalyzed Nucleophilic Trifluoromethylation of trans-Enones with Trimethyl(trifluoromethyl)silane:  A Facile Synthesis of trans-α-Trifluoromethyl Allylic Alcohols

  摘要：

  [GRAPHICS]Reactions of trans-enones, R-C=C-COR' (R = Ph, Me, -C=CH-CH=C-S; R' = Ph, Me, Pt, CFB) (la-e), with TMS-CF3 in the presence of catalytic amounts of cesium fluoride (CsF) in ethylene glycol dimethyl ether led to the formation of the corresponding trans-alpha-trifluoromethyl silyl ethers, R-C=C-C(OSiMe3)(CF3)R' (R = Ph, Me, -C=CH-CH=C-S; R' = Ph, Me, Pt, CFB) (2a-e), in essentially quantitative yield. On hydrolysis with aqueous HCl, the corresponding trans-alpha-trifluaromethyl allylic alcohols, R-C=C-C(OH)(CF3)R' (R = Ph, Me, -C=CH-CH=C-S; R' = Ph, Me, Et, CF3) (3a-e), were formed in >90% isolated yield. Under similar reaction conditions, 2-cyclohexen-1-one (1f) also gave trifluoromethyl allylic alcohols (3f) in 92% yield. The intermediates (2a-f) and products (3a-f) are liquids and were characterized by IR, H-1, (19)f and C-13 NMR, MS, and high-resolution mass spectroscopy (HRMS).

  Potassium alkoxide was found to be a highly active catalyst for the nucleophilic trifluoromethylation of carbonyl compounds. The catalytic system was successfully applied to the reactions of both aldehydes and ketones, affording the corresponding trifluoromethylated products in high yields at low catalyst loadings (0.1–0.01 mol%) in several solvents, such as THF, toluene, and CH2Cl2. In addition, the
