  • Keynote article. Nickel catalysed coupling of allylamines and boronic acids
    作者:Barry M. Trost、Michel D. Spagnol
    DOI:10.1039/p19950002083
    日期:——
    vinyl derivatives, E-isomers couple more efficiently than Z-isomers and both fully retain the geometrical integrity. Methylations preferably employ the boronic esters like 2-methyl-1,3,2-benzodioxaborole or 2-methyl-1,3,2-dioxaborolane rather than methylboronic acid. The stereochemistry of the reaction involves a net inversion with respect to the allylamine. The regioselectivity is a function of ligand
    烯丙胺在镍(0)催化剂而不是钯(0)催化剂存在下作为与硼酸交叉偶联的底物。芳基,乙烯基和甲基硼酸的作用良好。使用乙烯基衍生物,E异构体比Z偶联更有效-异构体和两者完全保留几何完整性。甲基化优选使用硼酸酯,例如2-甲基-1,3,2-苯并二恶唑硼酸酯或2-甲基-1,3,2-二氧杂硼烷,而不是甲基硼酸。反应的立体化学涉及烯丙基胺的净转化。区域选择性是配体的函数。通常,空间大的供体膦在取代度较低的位置促进新的C–C键形成。双齿配体,特别是1,1'-联萘-2,2'-双(二苯基次膦基)(BINAPO),可在取代度更高的烯丙基末端促进新的C–C键形成。与烯丙醇和与硼酸形成的酯相比,胺似乎是优选的伴侣,并具有更高的立体特异性。
  • Organoboranes. 56. Systematic study of the reactions of 1-alkenylboronic esters with representative organolithium and Grignard reagents to provide an efficient, selective synthesis of organyl-1-alkenylborinic esters
    作者:Herbert C. Brown、Nagarajan Vasumathi、Navalkishore N. Joshi
    DOI:10.1021/om00028a021
    日期:1993.4
    A selective reaction of the ''ate'' complexes formed with 1-alkenylboronic esters and organolithium or Grignard reagents, by treatment with either Bronsted or Lewis acids at -78-degrees-C to give the corresponding organylalkenylborinic esters, is explored in this study. This systematic, detailed study reveals that the nature of the alkoxy group on boron, the nature and the amount of the alkyllithium or Grignard reagent used, the solvent, the reaction temperature, and the nature and amount of the acid used all play significant roles in influencing both the yield and the selectivity achieved for the formation of the desired organylalkenylborinates. Optimized procedures for the syntheses of representative organylalkenylborinic esters in high yield are summarized.
