  Biheteroaromatic diphosphine oxides-catalyzed stereoselective direct aldol reactions

  摘要：

  A highly stereoselective direct aldol condensation of ketones to aromatic aldehydes was realized; the trichlorosilyl enolether generated in situ in the presence of tetrachlorosilane is activated by catalytic amounts of an enantiomerically pure biheteroaromatic phosphine oxide to react with aldehydes, coordinated as well as activated by the chiral cationic hypervalent silicon species. This Lewis acid-mediated Lewis base-catalyzed transformation allowed, starting from two carbonyl compounds, to directly synthesize beta-hydroxy ketones generally with high anti stereoselectivity and up to 93% ee for the anti isomer.

• Catalytic Anions Embedded into Avidin: Importance of Their Chirality and the Chiral Environment on the Stereocontrol of the Aldol Reaction
  作者：Vincent Gauchot、Andreea R. Schmitzer

  Several catalytic anions bearing a pseudo-dipeptide scaffold, in combination with a biotinylated imidazolium cation, were prepared. The assembly of these salts with avidin resulted in the formation of stable biohybrid catalysts, active in ionic liquid/aqueous media for the aldol reaction. By using natural and non-natural amino alcohols as “side chains” for the proline derivative anion, we studied the

  制备了带有伪二肽支架的几种催化阴离子，并结合了生物素化的咪唑鎓阳离子。这些盐与抗生物素蛋白的组装导致形成稳定的生物杂交催化剂，该催化剂在离子液体/水性介质中对醛醇缩合反应具有活性。通过使用天然和非天然氨基醇作为脯氨酸衍生物阴离子的“侧链”，我们研究了阴离子与其在亲和素中的位置之间的协同作用。利用阴离子在抗生物素蛋白内部的较大移动自由度，我们还研究了这种类型的生物杂交催化剂的底物范围。

  Highly syn-selective cross-aldol reaction of aldehydes has remained a challenging subject in the field of aminocatalysis. To achieve this end, chiral primary amines have been explored and the primary−tertiary diamine−Brønsted acid salts are found to promote the cross-aldol reactions of aldehydes with high activity and syn selectivity. Among various vicinal diamines screened, l-phenylalanine derived

  在氨基催化领域，醛的高度顺-选择性交叉-羟醛反应一直是具有挑战性的主题。为了达到这个目的，已经研究了手性伯胺，发现伯叔叔二胺布朗斯台德酸盐可以高活性和顺选择性地促进醛的交叉羟醛反应。在筛选的各种邻位二胺中，1-苯丙氨酸衍生的2a / TfOH共轭物被确定为最佳催化剂，显示出良好的催化活性（高达97％的产率）和高的合成选择性（syn / anti高达24：1、87％ee） 。当前的催化选择性地与较小的脂族醛供体（例如丙醛和异丁醛）一起起作用，但不适用于带有较大β-取代基（> Me）的脂族醛。另外，使用2a / TfOH共轭物也使糖醛供体的第一个顺-选择性交叉-羟醛反应成为可能。

  Direct catalytic aldol reactions of alpha,alpha-dialkylaldehyde donors and arylaldehyde acceptors have been performed using pyrrolidine-acetic acid bifunctional catalysts. This general and practical amine-acid combination was identified by screening catalysts using a new fluorescent detection system for carbon-carbon bond formation. Using 0.05 equiv of pyrrolidine and 0.25 equiv of acetic acid as catalyst, we obtained alpha,alpha-dialkylaldol product in 96% yield after 2 h at ambient temperature. Proline was a poor catalyst of this reaction.
