  Trimethylsilyl Trifluoromethanesulfonate- Accelerated Addition of Catalytically Generated Zinc Acetylides to Aldehydes

  摘要：

  In the presence of TMSOTf, a wide variety of terminal acetylenes add rapidly and efficiently to aldehydes via a catalytically generated zinc acetylide. In the absence of TMSOTf, no reaction is observed under otherwise identical conditions.

  Contrary to expectations, commercially available 2 M Me2Zn in toluene is able to promote the addition of phenylacetylene to aldehydes and ketones. This reactivity is determined by a new, unprecedented mechanism, which involves activation of the zinc reagent via coordination with carbonyl substrates that behave “ligand like”. Broad scope, high tolerance to functional groups, and a simple procedure make

  与预期相反，在甲苯中可商购的2 M Me 2 Zn能够促进将苯乙炔添加到醛和酮中。这种反应性是由一种新的，前所未有的机制决定的，该机制涉及通过与表现为“配体样”的羰基底物的配位来激活锌试剂。宽泛的范围，对官能团的高度耐受性以及简单的操作步骤使这种新方法对于合成化学家而言非常有趣。

  propargylic alcohols prepared from the catalytic asymmetric enyne addition to aliphatic aldehydes are used to prepare a series of optically active trienynes. In the presence of a catalytic amount of [RhCl(CO)2]2 and 1 atm of CO, the optically active trienynes undergo highly stereoselective domino Pauson–Khand/[4 + 2] cycloaddition to generate optically active multicyclic products. The Rh(I) catalyst

  Enantioselective alkynyl zinc additions to aromatic and aliphatic aldehydes have been studied using terpene derived chiral amino alcohol ligands. The limonene derived amino alcohol (1R,2R,5S)-2-methyl-5-(1-methylethenyl)-2-(1-pyrrolidinyl)cyclohexanol gave the most promising results. Chiral propargylic alcohols were obtained in good yields and moderate enantioselectivities (up to 60%).

  1,3-Diaryl-2-propynyl trimethylsilyl ethers were easy to isomerize into the corresponding siloxyallenes using a catalytic amount of potassium tert-butoxide under very mild conditions. The siloxyallenes reacted in situ with various aldehydes to afford Z-selective β-branched Morita–Baylis–Hillman-type adducts in a one-pot reaction after acid treatment.

  在非常温和的条件下，使用催化量的叔丁醇钾，很容易将1，3-二芳基-2-丙炔基三甲基甲硅烷基醚异构化成相应的甲硅烷氧基烯。硅氧丙二烯与各种醛原位反应，在酸处理后的一锅反应中提供Z选择性的β支化Morita–Baylis–Hillman型加合物。

  The 1,1‘-binaphthyl macrocycle (S)-2 is found to be an excellent catalyst for the alkyne addition to aldehydes. In the presence of (S)-2 (20 mol %) and Me2Zn (2 equiv) in THF at room temperature, the addition of phenylacetylene to linear or branched aliphatic aldehydes and vinyl aldehydes gave various propargylic alcohols with 89−96% ee.
