    One-Step Synthesis of Tetrazolo[1,5-a]pyrimidines by Cyclization Reaction of Dihydropyrimidine-2-thiones with Sodium Azide
    摘要:
    An novel, versatile and cost-effective approach for tetrazolo[1,5-a]pyrimidines and tetrazolo[1,5-a]quinazolines from cyclization reaction of dihydropyrimidinethiones with sodium azide in the presence of mercuric acetate is described. To compare this procedure with the conventional method, we carried out the cyclization reactions through direct functionalization of the pyrimidinethione core, which obtained from Biginelli 3,4-dihydropyrimidine-2-thiones or 4-aryl-7,7-dimethyl-5-oxo-1,2,3,4,5,6,7,8-octahydroquinazoline-2-thiones.

    T3P®-DMSO介导的一锅串联方法,从醇中合成3,4-二氢嘧啶-2(1H)-酮/硫酮
    摘要:
    背景:Biginelli反应是最重要的多组分化学反应之一,可产生3,4-dihydropyrimidin-2(1H)-ones。尽管有一个世纪以来使用不同的底物报道了Biginelli反应的报道,但文献中仍缺乏使用醇作为底物的例子。迄今为止,尚未探索用另一官能团取代醛组分。 方法:在本研究中,我们已使用丙基膦酸酐(T3P®)-DMSO作为从芳香族醇一锅合成3,4-二氢嘧啶-2(1H)-酮/硫酮的高效温和试剂。 结果:在温和的条件下,醇被原位氧化为醛,然后与β-酮酸酯和脲/硫脲进行三组分反应,生成3,4-二氢嘧啶-2(1H)-1 /硫酮。 结论:首次在温和的反应条件下以良好的收率首次从醇类直接合成3,4-二氢嘧啶-2(1H)-酮/硫酮。操作简便,成本低廉,试剂毒性小是该方案的主要优点。

  • Palladium-Catalyzed Copper-Promoted Hiyama-Type Carbon–­Carbon Cross-Coupling Reactions of Dihetaryl Disulfides as ­Electrophiles
    作者:Zheng-Jun Quan、Xi-Cun Wang、Ming-Xia Liu、Hai-Peng Gong
    DOI:10.1055/s-0036-1589116
    日期:2018.2
    Dihetaryl disulfides were used as electrophiles in a palladium-catalyzed carbon–carbon cross-coupling reaction with arylsilanes to ­realize a Hiyama-type reaction. This unique transformation shows high reactivity, excellent functional-group tolerance, and mild reaction conditions, making it an attractive alternative to conventional cross-coupling approaches for carbon−carbon bond construction.
