  • Rh(<scp>iii</scp>)-Catalyzed olefination to build diverse oxazole derivatives from functional alkynes
    作者:Yuan He、Ting Zheng、Yin-Hui Huang、Lin Dong
    DOI:10.1039/d1ob00507c
    日期:——
    A novel Rh(III)-catalyzed olefination reaction of oxazoles to generate diverse oxazole skeleton derivatives has been realized by directly using oxazole as the directing group. The reaction could tolerate many functional groups, affording complex oxazole derivatives with long chain alkenyls in moderate to good yields, which might find applications in the construction of diverse compounds.

  • Concerning Lewis Acid Promoted, Directing-Group-Free Epoxide-Ring-Opening Cascades
    作者:Timothy Jamison、Timothy Heffron
    DOI:10.1055/s-2006-949637
    日期:2006.9
    Lewis acid promoted cascades of a tris(disubstituted epoxide) triggered by silver-promoted abstraction of a bromide ion favors trans-dioxabicyclo[4.3.0]nonanes, rather than diads or triads of tetrahydropyrans (trams-dioxabicylco[4.4.0]decanes, for example). These results suggest that an epoxide-attacking-epoxonium mechanism is not operative in this system.
    路易斯酸促进了三(二取代环氧化物)的级联反应,由银促进的溴离子提取有利于反式二氧杂二环 [4.3.0] 壬烷,而不是四氢吡喃的二联体或三联体(反式二氧杂环 [4.4.0] 癸烷,例如)。这些结果表明环氧化物攻击环氧化物机制在该系统中不起作用。
  • <i>anti</i> ‐Selective Borylstannylation of Alkynes with ( <i>o</i> ‐Phenylenediaminato)borylstannanes by a Radical Mechanism
    作者:Kensuke Suzuki、Naoki Sugihara、Yoshihiro Nishimoto、Makoto Yasuda
    DOI:10.1002/anie.202201883
    日期:2022.7.4
    anti-borylstannylation of alkynes has been achieved by a radical mechanism with (o-phenylenediaminato)borylstannanes. This anti-addition manner is in contrast to the syn-selectivity in transition metal-catalyzed borylstannylation. 1-Boryl-2-stannylalkenes, which were applicable to sequential cross-coupling, were obtained with excellent regio- and stereoselectivity. The mechanism was revealed by DFT studies
    炔烃的第一个抗硼基锡烷化是通过使用(邻苯二氨基)硼基锡烷的自由基机制实现的。这种反加成方式与过渡金属催化的硼烷基化反应中的顺选择性相反。获得了适用于顺序交叉偶联的 1-Boryl-2-stannylalkenes,具有优异的区域选择性和立体选择性。DFT研究揭示了该机制。
