    摘要:
    描述了由双邻苯二甲酸锂催化的三甲氧基甲硅烷基烯醇醚的醛醇缩合反应。从环己酮衍生的无水条件下的三甲氧基甲硅烷烯醇醚醛醇缩合反应,得到主要的抗中度对映选择性加成物-aldol,而在含水条件下反应主要导致顺-adduct和的对映选择性合成-adduct被显着提高。在源自1-茚满酮的三甲氧基甲硅烷基烯醇醚与环己烷甲醛(97%ee(syn))的反应中获得最佳对映选择性。这是手性碱催化的三甲氧基甲硅烷基烯醇醚的醛醇缩合反应的第一个例子。

  • Enamine-Metal Lewis Acid Bifunctional Catalysis: Application to Direct Asymmetric Aldol Reaction of Ketones
    作者:Zhenghu Xu、Philias Daka、Ilya Budik、Hong Wang、Fu-Quan Bai、Hong-Xing Zhang

    Unprecedented bifunctional enamine–metal Lewis acid catalysts have been developed. In this bifunctional catalytic system, a tridentate ligand tethered with a chiral secondary amine was designed to solve the acid–base self-quenching problem leading to catalyst inactivation. This new bifunctional enamine–metal Lewis acid catalyst was found to catalyze aldol reactions of ketones efficiently in high yields

    The four-step synthesis of a chiral primary tertiary diamine salt, possessing a tropos dibenz[c,e]azepine ring is described. It is shown that 3.5–5 mol % of this salt is capable of promoting highly enantioselective crossed-aldol reactions between cyclohexanone and a series of aromatic aldehydes. In all cases, the aldol reactions proceed with high diastereoselectivity for the anti-aldol product. The

  • Molecular-Sieves Controlled Diastereo- and Enantioselectivity: Unexpected Effect in the Organocatalyzed Direct Aldol Reaction
    作者:Jun-An Ma、Xiao-Juan Li、Guang-Wu Zhang、Lian Wang、Ming-Qing Hua

    An efficient asymmetric organocatalyst was developed for the direct aldol reaction between ketones and aldehydes to afford β-hydroxy ketones in high stereoselectivity (anti/syn up to 92:8, ee up to >99%). The key of the success was the use of activated molecular sieves (4 ŠMS), which acted as a water scavenger. The influence of additives such as water or different types of molecular sieves on the reactivity and stereoselectivity of the reaction was also studied.

By performing the aldol reaction in [Bmim]NTf2 as a solvent, we report excellent isolated yields of the aldol product (up to 99%), as well as modest to excellent selectivities (dr superior to 99:1. ee up to 89%).
