β-Aminoethyltrifluoroborates: Efficient Aminoethylations via Suzuki−Miyaura Cross-Coupling
摘要:
A set of phenethylamines has been successfully prepared via Suzuki-Miyaura cross-coupling of diverse potassium beta-aminoethyltrifluoroborates with aryl halides. The potassium beta-aminoethyltrifluoroborates were easily prepared via hydroboration of enamine and enamide precursors.

just one PKCisoform, e.g., PKCδ, is sufficient to reduce UM cell proliferation. Therefore, we tested the effect of a recently described specific PKCδinhibitor, B106, on growth and survival of UM cell lines. Surprisingly, we found that B106 efficiently induced apoptosis in several cell lines, but apparently independent of activatedPKCδ.

facile and efficient phosphonylation of alkyl radicals under visible light photocatalytic conditions. Importantly, the ambiphilic nature of BecaP allows redox neutral reactions with both nucleophilic (activated by single-electron oxidation) and electrophilic (activated by single-electron reduction) alkyl radical precursors. Thus, a broad scope of feedstock alkyl potassium trifluoroborate salts and redox
碳磷键的形成在合成化学中具有重要意义,因为含磷化合物具有许多不可或缺的生化作用。虽然有多种方法可以获取有机磷化合物,但将易于获取的烷基进行膦酰化以形成脂肪族膦酸酯的情况很少见,并且在合成中并不常用。在此,我们介绍了一种新型磷自由基捕获剂“BecaP”,它能够在可见光光催化条件下轻松有效地对烷基自由基进行磷酰化。重要的是,BecaP 的两亲性质允许与亲核(通过单电子氧化激活)和亲电(通过单电子还原激活)烷基自由基前体发生氧化还原中性反应。因此,可以使用多种原料烷基三氟硼酸钾盐和氧化还原活性羧酸酯,每一类底物都通过不同的机制途径进行。温和的条件适用于将膦酸酯基序安装到药物和天然产物中,这一点通过巴氯芬(肌肉松弛剂)直接转化为苯氯芬(GABA B 拮抗剂)来证明。

Alkyl boronic acids and esters play an important role in the synthesis of C(sp3)-rich medicines, agrochemicals, and material chemistry. This work describes a new type of transition-metal-free mediated transformation to enable the construction of C(sp3)-rich and sterically hindered alkyl boron reagents in a practical and modular manner. The broad generality and functional group tolerance of this method
