  芳基二甲基硅烷醇酸酯对映选择性交叉偶联反应的手性双-配体的开发

  摘要：

  已经开发出使用1-萘基二甲基硅烷醇盐和手性双-配体的钯催化，对映体选择性的芳基-芳基交叉偶联反应。制备了包含各种2，5-二芳基吡咯烷基团的乙二醛双-配体家族，以评估配体结构对交叉偶联的速率和对映选择性的影响。开发了新的1-氨基-2,5-二芳基吡咯烷酮合成路线，以进行结构/反应选择性研究。芳基二甲基硅烷醇化物和芳基溴化物的角色逆转实验导致联芳基产品具有相同的构型和相似的对映选择性，这表明还原消除是立体确定的步骤。

  cyclic imines promoted by a chiral zinc complex is reported. In situ generated zinc‐ProPhenol complex with silane afforded pharmaceutically relevant enantioenriched 2‐aryl‐substituted pyrrolidines in high yields and with excellent enantioselectivities (up to 99% ee). The synthetic utility of presented methodology is demonstrated in an efficient synthesis of the corresponding chiral cyclic amines, being pharmaceutical

• Air and water stable secondary phosphine oxides as diazaphospholene precatalysts
  作者：Travis Lundrigan、Chieh-Hung Tien、Katherine N. Robertson、Alexander W. H. Speed

  DOI：10.1039/d0cc01072c

  日期：——

  Air-stable secondary phosphine oxides (SPOs) are readily formed from diazaphospholene bromides. In the presence of pinacolborane, these SPOs are transformed into catalytically active diazaphospholene hydrides. A silyl triflate transforms the SPOs into phosphenium triflates. The use of diazaphospholene SPOs as reduction reaction precatalysts was validated by imine reduction, conjugate reduction, pyridine

  The present disclosure discusses (i) a compound having a chemical formula according to Formula (I), or its enantiomer; and (ii) a compound that is reactive with a hydride to produce a compound having a chemical formula according to Formula (I), or its enantiomer. Formula (I) is: Formula (I) where R1 and R2 are H, optionally substituted C1-C3 alkyl, or linked together to form an optionally substituted C3 or C4 alkyl group; R3 and R3′ are H; R4 and R4′ are the same, and are optionally substituted C1-C6 alkyl; and R5 and R5′ are the same, and are optionally substituted aryl or heteroaryl. In some examples, R4 and R5 are linked, and R4′ and R5′ are linked, where both linking groups are the same.

• Enantioselective Thiourea-Catalyzed Cationic Polycyclizations
  作者：Robert R. Knowles、Song Lin、Eric N. Jacobsen

  DOI：10.1021/ja101256v

  日期：2010.4.14

  A new thiourea catalyst is reported for the enantioselective cationic polycyclization of hydroxylactams. Both the yield and enantioselectivity of this transformation were found to vary strongly with the identity of a single aromatic residue on a common catalyst framework, with more expansive and polarizable arenes proving optimal. Evidence is presented for a mechanism in which stabilizing cation-Pi interactions are a principal determinant of enantioselectivity.
