  Binaphthol-Catalyzed Asymmetric Conjugate Arylboration of Enones

  摘要：

  Conjugate addition of arylboronates to alpha,beta-unsaturated ketones may be catalyzed by chiral binaphthols with enantioselectivities of up to 99:1. Best results were observed with 3,3'-dichloro-BINOL. This chemistry was applied to syntheses of intermediates for syntheses of (+)-indatraline and (+)-tolterodine.

  Copper complexes of phosphoramidites efficiently catalyzed asymmetric addition of arylboron reagents to acyclic enones. Importantly, rare 1,4-insertion of arylcopper(I) was identified which led directly to O-bound copper enolates. The new mechanism is fundamentally different from classical oxidative addition/reductive elimination of organocopper(I) on enones.

  亚磷酰胺的铜配合物有效地催化芳基硼试剂向无环烯酮的不对称加成。重要的是，鉴定了稀有的芳基铜（I）的 1,4-插入，这直接导致了与 O 结合的铜烯醇化物。新机制与传统的有机铜（I）在烯酮上的氧化加成/还原消除有着根本的不同。

  The first Rh-diene-catalyzed aqueous asymmetric 1,4-addition of alpha,beta-unsaturated carbonyl compounds with arylboronic acids has been realized. By using a hydrophilic bicyclo[3.3.0] diene ligand, the reactions can be performed successfully in neat water at room temperature to afford the corresponding products in good yields and with very high enantioselectivities for both cyclic and linear substrates
