    SmI2-Promoted Reformatsky-Type Reaction and Acylation of Alkyl 1-Chlorocyclopropanecarboxylates
    摘要:
    In the presence of HMPA in THF, highly stereoselective Sml(2)-promoted substitutions of alkyl 1-chlorocyclopropanecarboxylates 1 using various ketones, aldehydes (Reformatsky-type reaction), and acyl chlorides (acylation) proceeded to give trans-adducts (2 or 5) in good to high yield with excellent trans-stereoselectivity (trans-add/cis-add = > 99/1). The Reformatsky-type reaction of 1 with aldehydes and unsymmetrical ketones proceeded with moderate diastereoselectivity (re-face-adduct/si-face-adduct = 60/40-75/25).

  • Aluminum enolates via retroaldol reaction: catalytic tandem aldol-transfer—Tischtschenko reaction of aldehydes with aldol adducts of ketones to ketones
    作者:Ilkka Simpura、Vesa Nevalainen
    DOI:10.1016/s0040-4020(03)01191-8
    日期:2003.9
    found to be efficient catalysts for aldol-transfer reactions of ketone to ketone aldol adducts with aliphatic or aromatic aldehydes giving rise to the formation of aldol adducts of ketones to the aldehydes. In the presence of an excess of an aliphatic aldehyde, a catalytic tandem aldol-transfer—Tischtschenko reaction is observed. The tandem reaction produces monoesters of 1,3-diols with high anti selectivity
    已发现衍生自双,联萘酚邻苯二酚的双齿铝螯合物是酮与酮的醛醇缩合醛与脂肪族或芳族醛的醛醇缩合反应的有效催化剂,从而形成了酮与醛的醛醇式加合物。在过量的脂族醛存在下,观察到催化串联的羟醛转移-Tischtschenko反应。串联反应产生具有高抗选择性和中等至良好化学产率的1,3-二醇单酯。1,2-不饱和醛在醛醇缩合反应中的反应性较低,与脂族和芳族醛相比,需要使用2–4倍高的催化剂负载量。在形成α-取代的羟醛和2-取代的单酯时观察到较差的非对映选择性。抗-1,3-二醇表明醛醇转移反应对所研究的催化剂不是非对映选择性的。已发现酰基单迁移限制了二醇单酯的高度1,3-抗选择性形成的效用。
  • Synthesis of allenic diols by samarium diiodide-promoted coupling between alkynyloxiranes and ketones
    作者:JoséM. Aurrecoechea、Eva Alonso、Mónica Solay

    日期:1998.4
    The SmI2-mediated reductive coupling between alkynyloxiranes and ketones provides a new route to 2,3-pentadiene-1,5-diols. The preferred stereochemistry observed in the coupling products is the result of the new CC bond forming anti with respect to the opening epoxide ring. Yields and diastereoselectivities are dependent on the alkynyloxirane substitution pattern.

    A compound of the formula (1) wherein R1 and R5 each represents an alkyl group having 1 to3 3 carbon atoms; R2, R3 and R4 each represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms and wherein the bonding at the 2-3 position is a single bond and that at the 3-4 position is a double when the substitution of hydroxy group is at the 5-position or the bonding at the 2-3 position is a double bond and that at the 3-4 position is a single bond when the substitution of hydroxy group is at the 7-position:; with the proviso that R2 and R4 should not be a hydrogen atom or an alkyl group simultaneously. Such a compound can be prepared by reacting resorcinol with an aliphatic ketone or a tertiary alcohol or by thermally decomposing polyalkyl (2, 4 - dihydroxyphenyl) hydroxychroman. The compound is useful as a herbicide and fungicide and as an intermediate for preparing agricultural chemicals.
