  瞬态硼酸的迭代反应可实现连续的C–C键形成

  摘要：

  以受控的顺序形成多个碳-碳键，从而以迭代方式快速建立分子复杂性的能力，是现代化学合成的重要目标。近年来，过渡金属催化的偶联反应在C–C键形成过程的发展中占主导地位。减少对贵金属的依赖的愿望以及获得金属杂质含量极低的产品的需求重新引起了人们对无金属偶联工艺的关注。在这里，我们就地报告通过流动产生的重氮化合物与硼酸反应制得了反应性烯丙基和苄基硼酸的制备方法，以及它们在受控的迭代式C-C键形成反应中的应用。到目前为止，我们已经显示出最多可以按顺序形成三个C–C键，包括用醛最终捕获反应性硼酸物质以产生一系列新的化学结构。

  Synthesis of some fenchyl-substituted alkenes and enol-ethers containing 3-oxyphenyl substituents by the Barton-Kellogg reaction

  摘要：

  The synthesis of one fenchyl-substituted alkene and two enol-ethers, containing 3-oxyphenyl substituents by the Barton-Kellogg reaction is described. The tri-substituted aromatic fenchyl-alkene 1a was prepared in 53% yield from thiofenchone and a diazoanisole; whereas enol-ethers 1b and 1c were obtained (95 and 75% yield, respectively) using an inverse approach based on diazofenchone and aromatic thionoesters. A mixture of Z and E isomers was obtained in all cases; isomer attribution and quantification has been carried out by analysis of NMR spectroscopic data assisted by theoretical calculations (E/Z ratio: 1a = 0.72, 1b = 2.2, 1c = 1.8). Reaction proceeds with low stereoselectivity leading to the preferential formation of diastereoisomeric olefins and enol-ethers where the aromatic substituent resides at the side of the two fenchyl methyl groups.

It is found (i) that the reactivities of the substrates decrease in the order of methanol, olefin and cyclohexane and (ii) that electron-donating substituents generally lead to reaction with

  We report herein the asymmetric coupling of flow‐generated unstabilized diazo compounds and propargylated amine derivatives, using a new pyridinebis(imidazoline) ligand, a copper catalyst and base. The reaction proceeds rapidly, generating chiral allenes in 10–20 minutes with high enantioselectivity (89–98 % de/ee), moderate yields and a wide functional group tolerance.

  Functionalized α-tertiary and -quaternary 2-arylcycloalkanones are rapidly accessed by scandium(III) triflate-catalyzed diazo­alkane-carbonyl homologations. Recent developments have allowed for carbon insertion reactions to be performed with catalyst loadings as low as 0.5 mol% on scales up to 5 mmol. Pairing readily available bis- and tris(oxazoline) based ligands with scandium triflate allows access to arylated medium ring carbocycles with enantioselectivities up to 98:2 er and >98% yield. The formal C-C insertion of aryldiazo­methanes into unsubstituted cycloalkanones provides a single-step solution to the ongoing challenge of α-arylation.
