  • Reactivite de lithiens derives d'ethers de la cyanhydrine du benzaldehyde vis-a-vis d'α-enones cycliques

    Conjugate addition of reagent 1A to 2-cyclohexenone 3 can be realized in THF-HMPT, so that one-pot conjugate addition—CH3I enolate trapping, leading to trans 2-methyl 3-benzoylcyclohexanone 17 can be easily performed. From isophorone 4 and Δ1(9)-2-octalone 5, 1, 4-addition under kinetic control is observed in THF. In the presence of HMPA, the reaction is under thermodynamic control. At low temperatures

    testosterone (1) and 10-methyl-Δ1,9-octalone-(2) (24) has been investigated in detail. The choice of reaction paths of both ketones depends strongly on the solvent used. In t-butanol, a photostationary equilibrium 1 ⇄ 3 is reached which is depleted solely by the parallel rearrangement 1 5 (Chart 1; for earlier results on these reactions see [2a] [6] [7]). In benzene, double bond shift 1 16 (Chart 3)
    共轭环己烯酮O-乙酰基睾酮(的光化学1)和10-甲基Δ 1,9 -octalone-(2)(24)进行了详细调查。两种酮的反应路径的选择在很大程度上取决于所用的溶剂。在叔丁醇中,达到了光平稳平衡1 solely 3,该平衡仅由平行重排1 5耗尽(图1;有关这些反应的更早结果,请参见[2a] [6] [7])。在苯中,发生双键移位1 16(图3),这是由于作为主要的光化学过程,被激发的酮的氧从基态酮中夺取了氢。在甲苯中,主要反应是通过向烯酮的β-碳中加氢而引入溶剂(图17 1,图4),伴随着双键转移和作为次要反应的饱和二氢酮的形成。与先前的报道[19]部分相反,双环烯酮24的光化学转化表现出相似的溶剂依赖性。相应的产品25 – 29汇总在表5和表1中。

  • New Method for Trifluoromethylation of Enolate Anions and Applications to Regio-, Diastereo- and Enantioselective Trifluoromethylation
    作者:Teruo Umemoto、Kenji Adachi
    DOI:10.1021/jo00098a030
    日期:1994.9
    Assessment was made of the effectiveness of different boron Lewis acids in mediating the trifluoromethylation of reactive enolate anions with S- and Se-(trifluoromethyl)chalcogen salts. Treatment of potassium or lithium enolates derived in situ from carbonyl compounds or enol trimethylsilyl ethers with S-(trifluoromethyl)dibenzothiophenium triflate (1) in the presence of 2-phenyl-1,3,2-benzodioxaborole (4) produced trifluoromethylated carbonyl compounds in high yields. Iq this manner, various alpha-CF3 ketones, gamma-CF3-alpha,beta-unsaturated ketones, and an alpha-CF3 ester were synthesized. Perfluorooctylation was similarly conducted using S-(perfluorooctyl)dibenzothiophenium triflate and 4. Thus, a balance of the reactivity of the reactants was essential for these electrophilic perfluoroalkylations. The deprotonation of 2-methylcyclohexanone with KN(SiMe(3))(2) followed by trifluoromethylation gave the 6-trifluoromethylated product regioselectively. In the trifluoromethylation of potassium enolate 16 of 4,4a,5,6,7,8-hexahydro-4a-methyl-2(3H)-naphthalenone, the use of bulky 2-mesitylphenanthro[9,10-d]-1,3,2-dioxaborole (15) led to the diastereo-selective formation of the thermodynamically less stable CF3-isomer 17 beta. For enantioselective trifluoromethylation, optically active (S)-4-phenyldinaphtho[2,1-d:1',2'-f][1,3,2]dioxaborepin(19) and its 3,3'-diphenyl derivative 20 were synthesized. The trifluoromethylation of the potassium enolate of propiophenone with 1 in the presence of 20 afforded optically active alpha-CF3-propiophenone in 45% ee yield. Thus, a new and versatile method for selective trifluoromethylation has been developed.
