Pd-catalyzed asymmetric Suzuki–Miyaura coupling reactions for the synthesis of chiral biaryl compounds with a large steric substituent at the 2-position

Beilstein Journal of Organic Chemistry, 2020
Pd-catalyzed asymmetric Suzuki–Miyaura couplings of 3-methyl-2-bromophenylamides, 3-methyl-2-bromo-1-nitrobenzene and 1-naphthaleneboronic acids have been successfully developed and the corresponding axially chiral biaryl compounds were obtained in very ...

Characterizations of the Suzuki tower near polygons [PDF]

, 2016
In recent work, we constructed a new near octagon $\mathcal{G}$ from certain involutions of the finite simple group $G_2(4)$ and showed a correspondence between the Suzuki tower of finite simple groups, $L_3(2) < U_3(3) < J_2 < G_2(4) < Suz$, and the ...

Nested symmetric representation of elements of the Suzuki chain groups

International Journal of Mathematics and Mathematical Sciences, 2003
We demonstrate an economic and concise method for representing the elements of groups involved in the Suzuki chain. For example, we represent each element of Suz:2 by a permutation on 14 letters from L3(2):2 followed by four words, each of length at most

Transition metal-catalysed A-ring C–H activations and C(sp2)–C(sp2) couplings in the 13α-oestrone series and in vitro evaluation of antiproliferative properties

Journal of Enzyme Inhibition and Medicinal Chemistry, 2021
Facile syntheses of 3-O-carbamoyl, -sulfamoyl, or -pivaloyl derivatives of 13α-oestrone and its 17-deoxy counterpart have been carried out. Microwave-induced, Ni-catalysed Suzuki–Miyaura couplings of the newly synthesised phenol esters with phenylboronic

Study on the Effect of the Ligand Structure in Palladium Organometallic Catalysts in the Suzuki–Miyaura Cross-Coupling Reaction

Chemistry Proceedings, 2021
In this communication, we present the results obtained using a family of cyclometallated palladium compounds as catalysts for the Suzuki–Miyaura cross-coupling reaction between an aryl halide and phenylboronic acid. We have studied the structural factors

On the involution fixity of exceptional groups of Lie type [PDF]

, 2018
The involution fixity ${\rm ifix}(G)$ of a permutation group $G$ of degree $n$ is the maximum number of fixed points of an involution. In this paper we study the involution fixity of primitive almost simple exceptional groups of Lie type. We show that if

Flow reactor synthesis of unsymmetrically substituted p-terphenyls using sequentially selective Suzuki cross-coupling protocols

Green Chemistry Letters and Reviews, 2019
Synthetic procedures, based on integrated flow chemical methods, have been developed for the sequential chemo-selective Suzuki–Miyaura cross-coupling of 1,4-dibromo-2-nitrobenzene (1) with various arylboronic acids.

Nickel-Catalyzed Carbon–Carbon Bond-Forming Reactions of Unactivated Tertiary Alkyl Halides: Suzuki Arylations [PDF]

, 2012
The first Suzuki cross-couplings of unactivated tertiary alkyl electrophiles are described. The method employs a readily accessible catalyst (NiBr[subscript 2]·diglyme/4,4′-di-tert-butyl-2,2′-bipyridine, both commercially available) and represents the ...
