  Structural Optimization of Enantiopure 2-Cyclialkylamino-2-aryl-1,1-diphenylethanols as Catalytic Ligands for Enantioselective Additions to Aldehydes

  摘要：

  The structural optimization of a family of modular, enantiopure beta-amino alcohol ligands with a common 2-amino-2-aryl-1,1-diphenylethanol skeleton, whose stereogenicity was introduced through the Jacobsen epoxidation of 1,1-diphenyl-2-arylethylenes, has led to the identification of a small set of optimal catalysts with enhanced activity and enantioselectivity in the addition of alkylzinc and arylzinc reagents to aldehydes. Criteria for the discrimination between apparently analogous, highly enantioselective ligands are proposed.

  N-甲苯磺酰腙与磷酸苄酯的 Pd 催化偶联：迈向二或三取代烯烃的合成

  摘要：

  该研究表明，通过将N-甲苯磺酰腙 (NTH) 与磷酸苄基作为亲电伙伴偶联，可以以良好至高产率获得各种具有高化学选择性的二取代和三取代烯烃。得到的新型催化体系由PdCl 2 (CH 3 CN) 2 /dppp、LiO t Bu为碱、环戊基甲基醚为绿色溶剂组成。此外，我们使用 NTH 衍生物和具有 C sp 2 -Cl 键的苄基磷酸酯进行了克级转化。后者被用作关键中间体进一步后功能化的起点。

• Electrochemical Aziridination by Alkene Activation Using a Sulfamate as the Nitrogen Source

  direct aziridination of triaryl‐substituted alkenes was achieved by means of an electrochemical process that could extend to multisubstituted styrenes. Specifically, hexafluoroisopropanol sulfamate was used as a nucleophilic nitrogen source. Mechanistic experiments suggest that this electrochemical process proceeds by stepwise formation of two C−N bonds through reactions between cationic carbon species

  三芳基取代的烯烃的第一次直接叠氮化是通过电化学方法实现的，该方法可以扩展到多取代的苯乙烯。具体而言，将六氟异丙醇氨基磺酸盐用作亲核氮源。机理实验表明，该电化学过程是通过阳离子碳物质与氨基磺酸盐之间的反应逐步形成两个C-N键而进行的。

  Pd-catalyzed reaction of N-tosylhydrazones with benzyl halides affords di- and trisubstituted olefins in high yields with excellent stereoselectivity. This coupling reaction is supposed to proceed through a migratory insertion of Pd carbene species.

  diazo(aryl)methyl(diaryl)phosphine oxides with aldehydes and ketones generates benzo-δ-phosphinolactones in low to good yields with 1,1-diarylalk-1-enes as byproducts under microwave irradiation. Diazo(aryl)methyl(diaryl)phosphine oxides first undergo a Wolff rearrangement to form diaryl(aryl)phosphenes, which further react with aldehydes and ketones to afford benzo-δ-phosphinolactones and β-phosphinolactones

  重氮（芳基）甲基（二芳基）氧化膦与醛和酮的反应生成苯并-δ-膦内酯，收率从低到高，1,1-二芳基烷-1-烯在微波照射下作为副产物。重氮（芳基）甲基（二芳基）氧化膦首先经历 Wolff 重排以形成二芳基（芳基）膦，其进一步与醛和酮反应生成苯并-δ-膦内酯和 β-膦内酯。后者在加热下不稳定并在反应条件下分裂成相应的1,1-二芳基烷-1-烯和芳基二氧化膦。芳基二氧化膦在后处理过程中变成芳基膦酸。环化中的选择性表明二芳基（芳基）膦与大多数醛和酮的反应有利于膦苯基参与（4 + 2）环化而不是（2 + 2）环化。

The obtained new catalytic system consisted of PdCl2(CH3CN)2/dppp, LiOtBu as a base, and cyclopentyl methyl ether as a green solvent. In addition, we performed a gram-scale transformation using NTH derivatives and benzylic phosphates having a C sp2–Cl bond. The latter was used as a starting
