α,β-Unsaturated amides are important building blocks and are key structural elements in a number of biologically active natural products. Despite their importance and prevalence, few methods exist to prepare conjugated amides directly and modularly. To address this gap, a titanium-promoted coupling of alkynes and isocyanates has been developed. The method is highly stereoselective, producing only the E isomer with good chemoselectivity and regioselectivity (>95/5), for unsymmetrical internal alkynes that contain a steric bias. The reactive titanacyclopentene intermediate formed from the coupling of the alkyne and isocyanate was additionally reacted with various electrophiles to access tetrasubstituted enamides.
Enantioselective synthesis of α-aminosilanes by copper-catalyzed hydroamination of vinylsilanes
Niljianskul, Nootaree,Zhu, Shaolin,Buchwald, Stephen L.
, p. 1638 - 1641 (2015/02/05)
The synthesis of α-aminosilanes by a highly enantio- and regioselective copper-catalyzed hydroamination of vinylsilanes is reported. The system employs Cu-DTBM-SEGPHOS as the catalyst, diethoxymethylsilane as the stoichiometric reductant, and O-benzoylhyd
Manganese(III)-mediated selective diphenylphosphinoyl radical reaction of 1,4-diaryl-1-butynes for the synthesis of 2-phosphinoylated 3,4- dihydronaphathalenes
Li, Da-Peng,Pan, Xiang-Qiang,An, Li-Tao,Zou, Jian-Ping,Zhang, Wei
, p. 1850 - 1855 (2014/03/21)
A diphenylphosphinoyl radical-initiated sequential reaction of 1,4-diaryl-1-butynes and analogues is developed for the synthesis of 2-phosphinoylated 3,4-dihydronaphathalenes and related compounds.
C(sp)-C(sp3) bond formation through cu-catalyzed cross-coupling of N -tosylhydrazones and trialkylsilylethynes
Ye, Fei,Ma, Xiaoshen,Xiao, Qing,Li, Huan,Zhang, Yan,Wang, Jianbo
supporting information; experimental part, p. 5742 - 5745 (2012/05/07)
Copper-catalyzed cross-coupling of N-tosylhydrazones with trialkylsilylethynes leads to the formation of C(sp)-C(sp3) bonds. Cu carbene migratory insertion is proposed to play the key role in this transformation.

Page/Page column 27-29, (2010/11/24)
A problem of the present invention is to provide an economical process with minimized toxicity for producing an aromatic compound having a variety of substituents such as various alkyl groups, and the problem is solved by a process for production of an aromatic compound represented by formula (1) below, which comprises reacting a compound represented by formula (2) below with an aromatic magnesium reagent represented by formula (3a) below in the presence of an iron catalyst and a diamine compound: wherein R is an optionally substituted hydrocarbon group or a C 3 - C 10 saturated or unsaturated ring group; A is an optionally substituted C 4 - C 20 aromatic group or an optionally substituted heteroaromatic group; X is a halogen atom or a sulfonic acid ester; and Y 1 is bromine, iodine, chlorine or a carbanion ligand.
Iron-catalyzed chemoselective cross-coupling of primary and secondary alkyl halides with arylzinc reagents
Nakamura, Masaharu,Ito, Shingo,Matsuo, Keiko,Nakamura, Eiichi
, p. 1794 - 1798 (2007/10/03)
Functional-group-compatible cross-coupling reaction of alkyl halides with arylzinc reagents takes place under iron catalysis in the presence of TMEDA, producing a variety of aromatic compounds in good to excellent yield. The pronounced effect of a magnesium salt was found to be the key to the promotion of the iron-catalyzed coupling reaction. Georg Thieme Verlag Stuttgart.
