  介孔铝硅酸盐催化的Mukaiyama醛和乙缩醛醛醇缩醛反应

  摘要：

  发现介孔铝硅酸盐（Al-MCM-41）是醛和缩醛与甲硅烷基烯醇醚或乙烯酮甲硅烷基缩醛反应以产生中等至高收率的相应羟醛加合物的有效多相催化剂。在反应中观察到Al-MCM-41对无定形二氧化硅-氧化铝和无铝介孔硅酸盐具有显着的高催化活性。固体酸催化剂可通过过滤容易地回收，并且回收的催化剂可在相同反应中重复使用，而不会显着降低催化活性。

  one-step Mukaiyama aldol-type reaction has been developed for the synthesis of beta-alkoxy carbonyl compounds starting from ketones and acetals/ketals. The reaction is mediated by a combination of Bu(2)BOTf and i-Pr(2)NEt affording the products in high yields. Formation of the two possible diastereoisomers of the beta-alkoxy ketones from the chiral acetals shows that the condensation takes place by an

  单步的Mukaiyama aldol型反应[反应：参见正文]已经开发了一种高效的单步的Mukaiyama aldol型反应，用于从酮和缩醛/缩酮开始合成β-烷氧基羰基化合物。通过Bu（2）BOTf和i-Pr（2）NEt的组合来介导反应，从而以高收率提供产物。由手性缩醛形成的两种可能的β-烷氧基酮的非对映异构体表明，缩合反应是通过S（N）1机理发生的，包括先将缩醛打开为氧离子。
• Mesoporous aluminosilicate-catalyzed Sakurai allylation and Mukaiyama aldol reaction of acetals

  In the presence of a catalytic amount of mesoporous aluminosilicate (Al-MCM-41), both allyltrimethylsilane and silyl enol ether reacted with various acetals under mild reaction conditions to afford the corresponding homoallyl ethers and beta-alkoxy ketones, respectively. The catalyst was easily recovered from the reaction mixture and could be reused in the same reaction without a significant loss of catalytic activity. Moreover, Al-MCM-41 exhibited high chemoselectivity for acetal over aldehyde in the reactions. (C) 2010 Elsevier Ltd. All rights reserved.

  日期：2003.1

  Mukaiyama-aldol reactions of carbonyl compounds with silyl enol ethers were well catalyzed on siliceous mesoporous materials (MCM-41). The reactivity of acetals was much higher than that of aldehyde. The reactions proceeded selectively at 273-298 K on the catalyst of 30 mg per mmol of the substrate.

  A mesoporous aluminosilicate (Al-MCM-41) was found to be an effective heterogeneous catalyst for the reaction of both aldehydes and acetals with silyl enol ethers or ketene silyl acetals to give the corresponding aldol adducts in moderate to high yields. The remarkable high catalytic activity of Al-MCM-41 over amorphous silica-alumina and aluminum-free mesoporous silicate was observed in the reaction
