  An Enantioselective Synthesis of 2-Aryl Cycloalkanones by Sc-Catalyzed Carbon Insertion

  摘要：

  Current methods for asymmetric alpha-arylation require blocking groups to prevent reaction at the alpha'-carbon, basic conditions that promote racemization, or multistep synthesis. This work records the first catalytic enantioselective examples of the diazoalkane-carbonyl homologation reaction. Medium ring 2-aryl ketones are prepared in one step in up to 98:2 er and 99% yield from the unsubstituted lower homologue by Sc-catalyzed aryldiazomethyl insertion with simple bis- and tris(oxazoline) ligands.

• A Brønsted Acid Catalyst for the Enantioselective Protonation Reaction
  作者：Cheol Hong Cheon、Hisashi Yamamoto

  DOI：10.1021/ja8041542

  日期：2008.7.1

  A highly reactive and robust chiral Brønsted acid catalyst, chiral N-triflyl thiophosphoramide, was developed. The first metal-free Brønsted acid catalyzed enantioselective protonation reaction of silyl enol ethers was demonstrated using this chiral Brønsted acid catalyst. The catalyst loading could be reduced to 0.05 mol % without any deleterious effect on the enantioselectivity.

  A new Lewis base-tolerant LBA (Lewis Acid Assisted Bronsted Acid) derived from La(OTf)(3) and (S)-HOP has been developed as a new chiral Bronsted acid. This acid has been successfully applied as a catalyst to asymmetric protonation reactions of silyl enol ethers of 2-substituted cyclic ketones.

  Weak is powerful: For the arylation of tin enolates, the palladium catalyst engages in weak CHO hydrogen bonds to control stereoselectivity (see scheme). Similar catalysts capable of NHO hydrogen bonding also works well.

  Reaction of lithium enolates of 2-arylcycloalkanones 2 with (R,R)-aminoborane 1, prepared from (1R,2R)-1,2-diaminocyclohexane 4 and PhBCl2, gives the corresponding optically active ketones 3 with up to 93% ee; this is the first example of enantioselective protonation using a metal-containing chiral proton source.

• Highly Efficient and Enantioselective α-Arylation of Cycloalkanones by Scandium-Catalyzed Diazoalkane-Carbonyl Homologation

  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.

  功能化的α-叔和α-季2-芳基环烷酮通过三氟甲磺酸钪(III)催化的重氮甲烷-羰基同系化反应迅速获得。最近的进展使得碳插入反应能够在催化剂负载量低至0.5 mol%的情况下进行，规模可达5 mmol。结合易于获得的基于双和三噁唑啉的配体与三氟甲磺酸钪，可以合成具有高达98:2 对映体比和>98%产率的芳基化中环碳环。芳基重氮甲烷在无取代环烷酮中的正式C-C插入提供了一种一步解决α-芳基化持续挑战的方法。
