  The proline-catalyzed asymmetric aldol reaction between aliphatic aldehydes and acetone has, to date, remained underdeveloped. Challenges in controlling this reaction include avoiding undesired side reactions such as aldol condensation and self-aldolization. In recent years we have developed optimized conditions, which enable high yields and good to excellent enantioselectivities, and which are presented

  迄今为止，脯氨酸催化的脂肪醛和丙酮之间的不对称醛醇反应仍未得到充分发展。控制该反应的挑战包括避免不希望的副反应，例如醛醇缩合和自醛醇化。近年来，我们开发了优化条件，可实现高产率和良好的对映选择性，并在本通讯中进行了介绍。

  an ester/amide exchange, and the use of the resulting β-hydroxy amide for the acylation of an organometallic compound. We shortened this route by showing that β-keto Weinreb amides are hydrogenated with up to 99 % ee in the presence of [Me2NH2]+[RuCl(S)-BINAP]2(µ-Cl)3}– (0.5 mol-%) at room temp./5 bar. These Weinreb amides were prepared by seemingly obvious yet unprecedented condensations of lithiated

  获得对映体纯 β-羟基酮的既定途径是通过 β-酮酯的不对称氢化、酯/酰胺交换以及将所得 β-羟基酰胺用于有机金属化合物的酰化。我们通过证明在 [Me2NH2]+[RuCl(S)-BINAP]2(µ-Cl)3}– (0.5 mol- %) 在室温/5 巴下。这些 Weinreb 酰胺是通过看似明显但前所未有的锂化 N-甲氧基-N-甲基乙酰胺与羧基氯化物的缩合反应制备的（产率 51-87%）。所得的 β-羟基 Weinreb 酰胺用于有机锂和格氏试剂的酰化。因此，他们得到了对映异构纯的 β-羟基酮（28 个例子）。这些化合物的选择产生了抗 1，

  Chiral organoaluminum complex 1 efficiently catalyzed the asymmetric hetero-ene reaction of commercially available 2-methoxypropene (2) with aldehydes under mild conditions to give the corresponding β-hydroxymethyl ketones 3 in good to excellent chemical yields with high enantiomeric excesses. The asymmetric catalysis of 1 was further applied to the carbonyl addition of methallylsilanes, where exclusive

  A variety of chiral bis-pyrroles have been made readily accessible via acid-catalyzed condensation of chiral ketones with pyrrole. Three representative chiral ketones 2-4 taken from the chiral pool were transformed into the corresponding bis-pyrrole derivatives in a straightforward acid-catalyzed condensation. Chiral β-hydroxy ketone derivatives, prepared through proline-catalyzed aldol condensation of acetone and an aldehyde, are readily transformed into the corresponding dipyrrolylmethane by the acid-catalyzed condensation carried out in the same conditions. The crystal structure of the chiral dipyrrolylmethane 2 derived from the (-)-menthone was determined.
