    Synthesis of Alkoxymethylene and Alkoxycarbonyl-oxymethylene Butyrolactones
    摘要:
    A previously published route to alpha-alkoxymethylenebutyrolactones has been shown to yield instead the corresponding carbonates. An alternative synthesis of the (E)-alkoxymethylene derivatives is described along with details of photoisomerisation to yield mixtures from which the (Z)-alkoxymethylene lactones can be obtained readily by chromatography.

  • TiCl<sub>4</sub>/Et<sub>3</sub>N-Mediated Condensation of Acetate and Formate Esters: Direct Access to β-Alkoxy- and β-Aryloxyacrylates
    作者:José María Álvarez-Calero、Zacarías D. Jorge、Guillermo M. Massanet
    DOI:10.1021/acs.orglett.6b03233
    日期:2016.12.16
    (E)-β-aryloxyacrylate moieties from acetate and formate esters promoted by the TiCl4/Et3N system is presented. The reaction is compatible with a broad range of structural skeletons and elapses through an unusual condensation pathway. Taking into account the obtained results, we propose a plausible mechanism involving a bimetallic titanium intermediate for this type of transformation.
    提出了一种由TiCl 4 / Et 3 N体系促进的乙酸酯和甲酸酯构建(E)-β-烷氧基-和(E)-β-芳氧基丙烯酸酯部分的方法。该反应与广泛的结构骨架相容,并通过不寻常的缩合途径而消失。考虑到所获得的结果,我们提出了一种可能的机制,其中涉及一种用于这种类型转化的双金属钛中间体。
  • Novel dienes from α-ylidene and α-alkoxylidene lactones. Useful intermediates for the synthesis of benzofurans
    作者:Alistair W. Murray、Neil D. Murray、Robert G. Reid
    DOI:10.1039/c39860001230
    日期:——
    Novel dienes, formed by reaction of α-ylidene and α-alkoxylidene lactones with the lithium salt of acetonitrile, are readily converted into benzofuran precursors by a highly regioselective (and in the case of the former derivatives) a highly stereoselective Diels–Alder reaction.
    由α-亚烷基和α-烷氧基亚内酯与乙腈的锂盐反应形成的新型二烯,通过高度区域选择性(对于以前的衍生物而言)和高度立体选择性的Diels-Alder反应,很容易转化为苯并呋喃前体。
