  • Regioselective Robinson Annulation Realized by the Combined Use of Lithium Enolates and Aluminum Tris(2,6-diphenylphenoxide) (ATPH)
    作者:Susumu Saito、Itsuro Shimada、Yusuke Takamori、Michiaki Tanaka、Keiji Maruoka、Hisashi Yamamoto

    日期:1997.7
    enolates derived from ketones to a variety of α,β-unsaturated ketones was realized in the presence of aluminum tris(2,6-diphenylphenoxide) (ATPH). In this reaction, ATPH can be used as a carbonyl protector of α,β-unsaturated carbonyl substrates upon complexation, which facilitates the regioselective 1,4-addition of lithium enolates to Michael acceptors. Similarly, dianions of β-dicarbonyl compounds undergo
    在三(2,6-二苯酚)铝(ATPH)存在下,实现了衍生自酮的烯醇与各种α,β-不饱和酮的迈克尔加成。在该反应中,ATPH 在络合后可用作 α,β-不饱和羰基底物的羰基保护剂,这促进了烯醇与迈克尔受体的区域选择性 1,4-加成。同样,β-二羰基化合物的二价阴离子使用ATPH作为反应的有效促进剂,顺利地进行迈克尔加成。随后的区域选择性、分子内醛醇缩合也被证明,导致双环碳环系统。通常在质子介质中进行的罗宾逊环化很难获得这样的系统。
  • Development of N,N-bis(perfluoroalkanesulfonyl)squaramides as new strong Brønsted acids and their application to organic reactions
    作者:Cheol Hong Cheon、Hisashi Yamamoto
    DOI:10.1016/j.tet.2010.03.120
    日期:2010.6
    l groups have been developed and applied to several organic reactions. These squaramides are bench-stable and exhibit much higher reactivities in several organic reactions than squaric acid itself. N,N-Bis(trifluoromethanesulfonyl)squaramide 2a was applied to the Mukaiyama aldol reaction and Mukaiyama Michael reaction. Mechanistic studies revealed that the Brønsted acid might be the predominant catalyst
    已开发出一种新的强布朗斯台德酸,其衍生自带有不同全氟烷烃磺酰基基团的方酸骨架,并已应用于多种有机反应中。这些方酰胺是稳定的,并且在几种有机反应中显示出比方酸本身更高的反应性。将N,N-双(三甲磺酰基)方酰胺2a用于Mukaiyama aldol反应和Mukaiyama Michael反应。机理研究表明,布朗斯台德酸可能是通过酸本身而不是甲硅烷基化的布朗斯台德酸直接使羰基化合物质子化的主要催化剂。该酸2a的效用进一步扩展到细索-樱井烯丙基醛化和羰基-烯反应。此外,已经开发了具有更长的全氟烷基链的其他方酸酰胺2b和c,它们也是稳定的并且在几种有机反应中显示出与方酸酰胺2a类似的反应性。
  • A new Brønsted acid derived from squaric acid and its application to Mukaiyama aldol and Michael reactions

    of silyl enol ether. The Brønsted acid was further applied to Mukaiyama Michael reaction of α,β-unsaturated ketones. It is noted that catalyst loading of all Mukaiyama reactions was only 1 mol % or less, which demonstrated the high reactivity of this acid. Mechanistic studies implied that the Mukaiyama aldol reaction might proceed through Brønsted acid catalysis, rather than through Lewis acid catalysis
    双ñ制备了三稳定的强布朗斯台德酸-三甲磺酰基方酸酰胺,并将其用于布朗斯台德酸催化的甲硅烷基烯醇醚的Mukaiyama醇醛和迈克尔反应。以定量收率获得了所得的Mukaiyama醛醛缩醛产品,而该Brønsted酸在酮类中的用途扩展仅限于缺电子的酮类,这可能是由于酮的反应性较低以及甲硅烷基烯醇醚的竞争性去甲硅烷基化。将布朗斯台德酸进一步用于α,β-不饱和酮的Mukaiyama Michael反应。值得注意的是,所有Mukaiyama反应的催化剂负载量仅为1mol%或更低,这表明该酸具有高反应性。机理研究表明,Mukaiyama aldol反应可能会通过Brønsted酸催化进行,
  • Organotin triflate as practical catalyst for Michael addition of enol silyl ethers
    作者:Tsuneo Sato、Yoshiyuki Wakahara、Junzo Otera、Hitosi Nozaki
    DOI:10.1016/s0040-4020(01)80717-1
    日期:1991.12
    Dityltin bis(triflate) is a mild Lewis acid which catalyzes clean Michael addition of enol silyl ethers. The new catalyst allows to employ various labile acceptors such as methyl vinyl ketone and 2-cyclopentenone which do not undergo smooth reaction with conventional Lewis acids. A variety of enol silyl ethers are also employable and thus 2-(trimethylsiloxy)propene, the simplest one in this class of
    Dityltin bis(triflate)是一种温和的路易斯酸,可催化烯醇甲硅烷基醚的干净迈克尔加成反应。该新催化剂允许使用各种不稳定的受体,例如甲基乙烯基酮和2-环戊烯酮,它们不会与常规的路易斯酸进行平滑反应。也可以使用多种烯醇甲硅烷基醚,因此可以使用在这类化合物中最简单的2-(三甲基甲硅烷氧基)丙烯。环烷酮的烯醇甲硅烷基醚与乙烯基酮的加合物易于环化,得到所需的无异构体的环烯酮。因此,已经实现了鲁滨逊环行的实用版本。
  • Indium-trichloride catalyzed Michael reaction of silyl enol ethers with α,β-unsaturated carbonyl compounds under neat condition
    作者:Teck-Peng Loh、Lin-Li Wei
    DOI:10.1016/s0040-4020(98)00394-9
    日期:1998.6
    In the presence of a catalytic amount of indium (III) trichloride (InCl3) (20 mol%), ketene silyl enol ethers react quickly with α,β-unsaturated ketones and esters to afford the corresponding Michael adducts in moderate to good yields. Indium(III) trichloride can be recovered and reused without decrease in yields.
    在催化量的三氯化铟(III)(InCl 3)(20摩尔%)的存在下,乙烯酮硅烷基烯醇醚与α,β-不饱和酮和酯快速反应,以中等至良好的产率提供相应的迈克尔加合物。可以回收三氯化铟(III),而不会降低产量。
