    MIDA酰基硼酸酯与O -Me羟胺的合成及化学选择性连接
    摘要:
    N-甲基亚氨基二乙酰基(MIDA)酰基硼酸酯在水中与O- Me羟胺(包括未保护的肽底物)进行化学选择性酰胺键形成连接。这些稳定的硼酸盐很容易在一个步骤中由酰基三氟硼酸钾(KAT)制备。MIDA酰基硼酸酯与O-烷基羟胺的反应性-与KAT不反应-归因于中性MIDA硼酸酯与离子KAT的性质,导致可能的中间体稳定性和消除倾向不同。

    Synthesis of Acyltrifluoroborates
    摘要:
    Acylboranes are among the most elusive boron-containing organic functional groups, a fact that has impeded development of new reactions employing them as substrates. A new synthesis of acyltrifluoroborates from benzotriazole (Bt)-based N,O-acetals has been developed. Two other routes provide acyltrifluoroborates containing alcohols, aldehydes, and carbamates. The ketone-like reactivity of the acyltrifluoroborate functional group is demonstrated, and the first X-ray structure of an acyltrifluoroborate is reported.

  • Concise Synthesis of Potassium Acyltrifluoroborates from Aldehydes through Copper(I)‐Catalyzed Borylation/Oxidation
    作者:Jumpei Taguchi、Takumi Takeuchi、Rina Takahashi、Fabio Masero、Hajime Ito
    DOI:10.1002/anie.201901748
    日期:2019.5.27
    subsequent oxidation. This synthetic route is characterized by the wide range of aldehydes accessible, favorable step economy, mild reaction conditions, and tolerance of various functional groups, and it enables the facile generation of a range of KATs, for example, bearing halide, sulfide, acetal, or ester moieties. Moreover, this method was applied to the three‐step synthesis of various α‐amino acid analogues
    酰基三硼酸(KAT)是通过(I)催化的醛化化和随后的氧化反应制得的。这种合成路线的特点是可利用的醛类广泛,有利的步骤经济性,温和的反应条件以及对各种官能团的耐受性,并且能够轻松生成各种KAT,例如带有卤化物,硫化物乙缩醛,或酯部分。此外,通过使用天然氨基酸作为起始原料,该方法应用于三步合成各种在C末端带有KAT部分的α-氨基酸类似物。
  • Catalytic Synthesis of Potassium Acyltrifluoroborates (KATs) through Chemoselective Cross‐Coupling with a Bifunctional Reagent

    日期:2019.8.5
    Potassium acyltrifluoroborates (KATs) are increasingly important functional groups, and general methods for their preparation are of great current interest. We report a bifunctional iminium reagent bearing both a tin nucleophile and a trifluoroborate, which was applied in chemoselective Pd0‐catalyzed Migita–Kosugi–Stille cross‐coupling reactions owith aryl and vinyl halides. This method gives access
    酰基三硼酸(KAT)是越来越重要的官能团,制备它们的通用方法引起了人们的极大兴趣。我们报道了一种带有亲核试剂和三硼酸盐的双功能亚胺试剂,该试剂已用于Pd 0催化的Migita-Kosugi-Stille交叉偶联反应,以及芳基和卤代乙烯。这种方法可以访问以前难以获得的芳族和α,β-不饱和酰基三硼酸酯,包括氨基酸衍生的KAT的前体。
  • Amide-Forming Ligation of Acyltrifluoroborates and Hydroxylamines in Water
    作者:Aaron M. Dumas、Gary A. Molander、Jeffrey W. Bode
    DOI:10.1002/anie.201201077
    日期:2012.6.4
    Come together, right now: Acyltrifluoroborates and O‐benzoyl hydroxylamines come together to form amides in water (see scheme). The ligations are complete within minutes at room temperature and do not require any reagents or catalysts. The reaction has a broad substrate scope and tolerates unprotected functional groups.

    developed a one-step synthesis of acylborons from both readily available acyl chlorides and bis(pinacolato)diboron through copper(I)-catalyzed borylation. Under the reaction conditions using tBuOLi, polystyrene-supported triphenylphosphine as a copper ligand was found to promote the borylation of acyl chlorides while suppressing alcoholysis. This method enables the facile synthesis of potassium acyltrifluoroborates
    我们开发了一种通过 (I) 催化的化反应从容易获得的酰和双 (频哪醇) 二中一步合成酰的方法。在使用t BuOLi 的反应条件下,发现聚苯乙烯负载的三苯基膦作为配体可促进酰化,同时抑制醇解。该方法能够轻松合成酰基三硼酸
