  • Reactions and Mechanistic Studies of Rhenium-Catalyzed Insertion of α,β-Unsaturated Carbonyl Compounds into a C–H Bond
    作者:Yoichiro Kuninobu、Yuta Nishina、Kayo Okaguchi、Makoto Shouho、Kazuhiko Takai
    DOI:10.1246/bcsj.81.1393
    日期:2008.11.15
    A rhenium complex, [ReBr(CO) 3 (thf)] 2 , catalyzes the insertion of α,β-unsaturated carbonyl compounds into a C-H bond of aromatic compounds having nitrogen-containing directing groups. In this reaction, Re 2 (CO) 10 can also be used as a catalyst. When imines are employed as the aromatic substrates, sequential cyclization proceeds and indene derivatives are obtained in good to excellent yields. This

  • Regio- and stereoselective addition of organolithiums to naphthalenes. an efficient synthesis of 11,2-trisubstituted and trans-2-disubstituted dihydronaphthalenes
    作者:A.I. Meyers、Kathryn A. Lutomski、Dominique Laucher
    DOI:10.1016/s0040-4020(01)85942-1
    日期:1988.1
    The addition of a variety of organolithium reagents to 1-napththyloxazolines and 2-naphthyloxazolines followed by trapping with electrophiles leads to high yields of the title compounds. Very high stereoselectivity characterizes the present process in that the electrophile enters from the naphthalene face opposite to the entry of the organolithium reagent. A number of organolithiums have been investigated
    将多种有机锂试剂添加到1-萘恶唑啉和2-萘恶唑啉中,然后用亲电试剂捕集,可得到高产率的标题化合物。很高的立体选择性是本发明方法的特征,因为亲电试剂从与有机锂试剂进入相反的萘面进入。已经研究了许多有机锂,并且发现从四取代的锡烷原位生成有机锂提供了用于将亲核加成到萘中的优良试剂。恶唑啉的去除有效地导致了甲酰基或羟甲基-1,2-二氢萘。
  • Palladium-catalyzed electrophilic C–H fluorination of arenes using oxazoline as a removable directing group
    作者:David A. Gutierrez、Wan-Chen Cindy Lee、Yuning Shen、Jie Jack Li
    DOI:10.1016/j.tetlet.2016.10.079
    日期:2016.11
    Dimethyloxazoline was rationally designed to act as a removable ortho-directing group (DG) for the palladium-catalyzed C–H electrophilic fluorination of arenes. Using NFSI as the fluorinating agent, and Pd(II), Ag(I) catalytic system, electrophilic C(sp2–H) ortho-fluorination took place on a variety of aryl substrates to afford the corresponding mono- and di-fluorinated products.
    二甲基恶唑啉经过合理设计,可作为钯可催化芳烃的C–H亲电氟化反应的可移动邻位导向基团(DG)。使用NFSI作为氟化剂,以及Pd(II),Ag(I)催化体系,亲电C(sp 2 -H)邻位氟化反应在各种芳基基质上进行,从而得到相应的单氟化和二氟化产物。

    4-Methyloxazole and 4,4-dimethyl-2-oxazoline were treated with n-butyllithium and trimethyltin chloride to give the corresponding 2-trimethylstannyl derivatives which in the presence of tetrakis(triphenylphosphine)palladium(0) as a catalyst undergo cross-coupling reactions with various aryl and heteroaryl halides to give 2-aryl and 2-heteroaryl oxazoles and oxazolines in high yields.

  • Secondary Phosphine Oxide Preligands for Palladium-Catalyzed C-H (Hetero)Arylations: Efficient Access to Pybox Ligands
    作者:Debasish Ghorai、Valentin Müller、Helena Keil、Dietmar Stalke、Giuseppe Zanoni、Boryslav A. Tkachenko、Peter R. Schreiner、Lutz Ackermann
    DOI:10.1002/adsc.201700663
    日期:2017.9.18
    C–H arylations of oxazolines were accomplished with a well‐defined palladium catalyst derived from a secondary bisdiamantyl phosphine oxide. The single‐component secondary phosphine oxide (SPO)‐palladium complex enabled C–H activations with aryl bromides and challenging aryl chlorides in the absence of directing groups, setting the stage for the step‐economical synthesis of pybox ligands under racemization‐free
    恶唑啉的C–H芳基化反应是使用衍生自仲双双金刚烷基氧化膦的明确定义的钯催化剂完成的。单组分仲氧化膦(SPO)-钯配合物可在没有引导基团的情况下用芳基溴化物和具有挑战性的芳基氯化物进行C-H活化,为在无消旋反应条件下逐步经济地合成pybox配体奠定了基础。
