    一锅无金属的方案,由1,4-二烯和硫醇合成硫属元素呋喃
    摘要:
    在催化量的对甲苯磺酸存在下,通过1,4-二烯的硫醇-迈克尔/帕尔-克诺尔顺序硫醇化反应,可以无硫金属化合成硫属呋喃。目前的一锅策略涉及以反马尔可夫尼可夫的方式将巯基迈克尔加成1,4-二烯,形成新的C–S键,然后在猫的存在下进行分子内脱水环化。TsOH可以完全取代呋喃,产率高至优异(50–99%)。该反应可与多种底物相容,并且还可以硫代呋喃的数克级合成。

    Target-oriented synthesis: miscellaneous synthetic routes to access 1,4-enediones through the coupling of 1,3-dicarbonyl compounds with multiform substrates
    摘要:
    Target-oriented synthetic protocol was presented for the synthesis of 1,4-enediones. The approach can efficiently construct 1,4-enediones through different reaction pathways from multiform substrates alpha-halo aromatic ketones, 2-hydroxy-aromatic ketones and methyl carbinols. In this reaction, CuI was found to be the most efficient catalyst. Multiform substrates were also found to perform well to afford the products in a one-pot fashion. (C) 2013 Elsevier Ltd.
