  Mesoporous aluminosilicate-catalyzed allylation of carbonyl compounds and acetals

  摘要：

  A mesoporous aluminosilicate (Al-MCM-41) was found to be an effective heterogeneous catalyst for the reaction of both carbonyl compounds and acetals with allylsilanes to afford the corresponding homoallyl silyl ethers and homoallyl alkyl ethers, respectively. Both the mesoporous structure and the presence of aluminum moiety were indispensable for the high catalytic activity of Al-MCM-41. Moreover, Al-MCM-41 could catalyze the reaction of acetals chemoselectively in the presence of the corresponding carbonyl compounds. The solid acid catalyst Al-MCM-41 could be recovered easily by filtration and could be reused three times without a significant loss of catalytic activity. (C) 2011 Elsevier Ltd.

• Catalytic Use of Elemental Gallium for Carbon–Carbon Bond Formation
  作者：Bo Qin、Uwe Schneider

  DOI：10.1021/jacs.6b06767

  日期：2016.10.12

  The first catalytic use of Ga(0) in organic synthesis has been developed by using a Ag(I) cocatalyst, crownether ligation, and ultrasonic activation. Ga(I)-catalyzed C-C bond formations between allyl or allenyl boronic esters and acetals, ketals, or aminals have proceeded in high yields with essentially complete regio- and chemoselectivity. NMR spectroscopic analyses have revealed novel transient Ga(I)

  Ga(0) 在有机合成中的首次催化应用是通过使用 Ag(I) 助催化剂、冠醚连接和超声活化开发的。Ga(I) 催化的烯丙基或丙二烯基硼酸酯与缩醛、缩酮或胺缩醛之间的 CC 键形成以高产率进行，具有基本上完全的区域选择性和化学选择性。核磁共振光谱分析揭示了新的瞬态 Ga(I) 催化物质，分别通过 Ga(0) 和 B-Ga 金属转移的部分氧化原位形成。已经证明了不对称 Ga(I) 催化的可能性。
• Trimethylsilyl Trifluoromethanesulfonate Catalyzed One-Pot Method for the Conversion of Aldehydes to Homoallyl Ethers in an Ionic Liquid

  A mild method for the trimethylsilyl trifluoromethanesulfonate (TMSOTf) catalyzed one-pot synthesis of homoallyl ethers from aldehydes has been developed in the ionic liquid 1-butyl-3-methylimidazolium trifluoromethanesulfonate ([bmim] [OTf]). The advantages of this method include the use of a recyclable ionic liquid, facile product isolation without employing excess organic solvent, elimination of an aqueous waste stream, and mild reaction conditions.

  Iron(III) chloride-catalyzed effective allylation reactions of acetals with allyltrimethylsilane proceeded smoothly in high to excellent yields. In addition, this method could be applied to the one-pot synthesis of homoallyl benzyl ethers by a combination of dibenzyl acetalization of aldehydes and consecutive allylation of dibenzyl acetals.

  Scandium triflate catalyzes efficiently the allylation reactions of acetals and gem-diacetates with allyltrimethylsilane at ambient temperature to afford the corresponding homoallyl ethers and acetates in high yields. Also it is found to be effective for the direct formation of homoallyl ethers from aldehydes and allylsilane in presence of trimethylorthoformate.
