  Rh（I）催化的无CO气体氨基羰基化反应合成3-取代的异吲哚满酮

  摘要：

  描述了手性3-取代的异吲哚满酮骨架的高效且容易获得的合成。合成涉及硼酸经Rh（I）催化的不对称芳基化成2-卤代苯丙二胺，随后使用醛作为羰基源，经Rh（I）催化的所得2-卤代苄胺的分子内氨基羰基化。该方法可耐受多种官能团，以中等至高收率和高ee值产生异吲哚啉酮衍生物。另外，通过在Rh（I）催化的不对称芳基化之后简单地添加配体和醛，可以在一个锅序列中有效地完成两个Rh（I）催化的转化，以得到手性异吲哚啉酮。

  on a hexamethyl-1,1′-spirobiindane scaffold was accomplished starting from Bisphenol C. The optimal ligand could serve as an elegant chiral bidentate ligand in the Rh-catalyzed asymmetric 1,2-addition of organoboronic acids to various acyclic/cyclic aldimines, leading to chiral amines with high yields and excellent enantioselectivities.

  palladium-catalyzed, enantioselective three-component synthesis of α-arylamines starting from sulfonamides, aldehydes, and arylboronic acids has been developed. These reactions generate a wide array of α-arylamines with high yields and enantioselectivities. Notably, this process is tolerant to air and moisture, providing an operationally simple approach for the synthesis of chiral α-arylamines.

  first time, we report the application of [RuCl2(η6-p-cymene)]2 in the arylation of N-activated aldimines with boronic acids and its derivatives to afford chiral amines, which are important intermediates in the syntheses of key bioactive compounds. The behavior of the chiral ligands, the imine substrates, and the organoboron reagents were studied. Very good enantioselectivities were obtained.

  A nickel-catalyzed enantioselective transfer hydrogenation and deuteration of N-sulfonyl imines was developed. Excellent α-selectivity and high deuterium content were achieved by using inexpensive 2-propanol-d8 as a deuterium source. As a highlight, no deuteration of β-C–H and the remote C–H of N-sulfonyl amines occurred, which is hard to achieve using other imines or by hydrogen isotope exchange with

  Enantiomerically enriched tosyl-protected diarylmethylamines were rapidly prepared by the asymmetric addition of arylboronic acids to N-tosylaldimines under mild conditions in the presence of a catalyst prepared in situ from Rh(I) and a chiral diene ligand. This methodology offers access to diarylmethylamines in good yields with excellent chiral purity at room temperature using MeOH as a solvent and
