    名称:
    Highly enantioselective synthesis of long chain alkyl trifluoromethyl carbinols and β-thiotrifluoromethyl carbinols through lipases
    摘要:
    Among a variety of lipases tested, Candida antarctica lipase has been found to promote the enantioselective acylation of long chain alkyl trifluoromethyl carbinols 1a-4a and beta-thiotrifluoromethyl carbinols 5a-7a, producing both R and S enantiomeric alcohols in good to excellent chemical yield and enantioselectivity. In all cases the lipase preferentially acylates the S enantiomer, irrespective the presence or not of a sulfur atom in beta position to the hydroxyl group, When the reaction was carried out on the non-fluorinated substrates 1c-2c, the process occurred much faster and with higher e.e. of the less reacting enantiomer than when conducted on the fluorinated substrates.

  • An efficient and expeditious synthesis of functionalized trifluoromethyl ketones through lithium-iodine exchange reaction
    作者:Isabel Villuendas、Alfredo Parrilla、Angel Guerrero

    日期:1994.1
    long-chain triflouromethyl ketones achieved by metallation of the corresponding iodides in the presence of an equimolar amount of tert-butyllithium, followed by reaction with a fluoroacylating agent. Metallation occurs quantitatively at −78°C and, in contrast to what has been generally recommended, there is no need to add the second equivalent of base, since its presence may be detrimental if other electrophilic
    通过在等摩尔量的叔丁基锂存在下将相应的化物属化,然后与代酰化剂反应,可以实现长链三甲基酮的直接高效合成。属化在-78°C下定量发生,与通常所建议的相反,不需要添加第二当量的碱,因为如果分子中存在其他亲电子功能,则其存在可能是有害的。

    α-Trifluoromethyl amines (IV) were prepared in three steps: preparation of α-trifluoromethyl ketones (I), their conversion tobenzyloximes (II), and reduction of the oximes (II) with lithium aluminium hydride and sodium methoxide. For example, α-trifluoromethyltridecylamine was obtained from the reduction of trifluoromethyl dodecyl ketone benzyl oxime.

    Despite the very low acidity of the inert α C−H bonds (pKa≈42.6), direct asymmetric α-C(sp3)−H addition of N-unprotected propargylic amines to trifluoromethyl ketones has been achieved by using a chiral pyridoxal as the carbonyl catalyst, producing a broad variety of chiral alkynyl β-aminoalcohols in high yields with excellent stereoselectivities (up to 84 % yield, >20 : 1 dr, 99 % ee).
    尽管惰性 α C−H 键的酸度非常低 (p K a ≈ 42.6),但通过使用手性吡哆醛,已经实现了 N-未保护的炔丙胺与三甲基酮的直接不对称 α-C( sp 3 )−H 加成作为羰基催化剂,以高产率和出色的立体选择性(高达 84% 产率,>20:1 dr,99% ee)生产多种手性炔基 β-基醇。

    日期:2023.9.18
    Catalytic methods for direct access to aliphatic trifluoromethyl ketones from feedstocks remain underdeveloped, partially owing to the high reactivity and instability of the trifluoroacetyl radical. Reported herein is the photocatalytic synthesis of trifluoromethyl ketones from alkyl bromides and trifluoroacetic anhydride. The reaction features visible-light catalysis and halogen-atom transfer (XAT)
