Arylation of rhodium(II) azavinyl carbenes with boronic acids.
نویسندگان
چکیده
A highly efficient and stereoselective arylation of in situ-generated azavinyl carbenes affording 2,2-diaryl enamines at ambient temperatures has been developed. These transition-metal carbenes are directly produced from readily available and stable 1-sulfonyl-1,2,3-triazoles in the presence of a rhodium carboxylate catalyst. In several cases, the enamines generated in this reaction can be cyclized into substituted indoles employing copper catalysis.

Copper-catalyzed sequential N-arylation of C-amino-NH-azoles.
Copper(II)-catalyzed boronic acid promoted C-N bond cross-coupling reactions have been successfully developed for sequential N-arylation of C-amino-NH-azoles. These general protocols are compatible with a variety of aryl/hetero-aryl boronic acids and provided rapid access to a diverse array of diarylaminoazole derivatives in a two-step sequence or in one-pot.
متن کاملCopper(II)-Mediated O-Arylation of Protected Serines and Threonines
An effective protocol toward the O-arylation of β-hydroxy-α-amino acid substrates serine and threonine has been developed via Chan-Lam cross-coupling. This Cu(II)-catalyzed transformation involves benign open-flask conditions that are well-tolerated with a variety of protected (Boc-, Cbz-, Tr-, and Fmoc-) serine and threonine derivatives and various potassium organotrifluoroborates and boronic ...
متن کاملPalladium(II)-catalyzed meta-selective direct arylation of O-β-naphthyl carbamate.
Selective meta-arylation of O-β-naphthyl carbamate has been accomplished using Pd(OAc)2 as a catalyst precursor and K2S2O8 with AgOAc as the oxidant. A range of aryl boronic acids could be introduced in moderate to good yields. Mechanistic investigation shows that the carbamate substituent has a unique effect and the reaction undergoes an ortho-carbometallation/meta-direct arylation process.

Using asymmetric catalysis to simultaneously form carbon-carbon bonds and generate single isomer products is strategically important. Suzuki-Miyaura cross-coupling is widely used in the academic and industrial sectors to synthesize drugs, agrochemicals and biologically active and advanced materials. However, widely applicable enantioselective Suzuki-Miyaura variations to provide 3D molecules re...

The highly regioselective ortho-arylation of acetanilides with aromatic boronic acids in the presence of a Ru(II) complex (3 mol%), AgSbF6 (12 mol%), Cu(OTf)2 (20 mol%) and Ag2O (1.0 eq.) is described. Later, ortho-arylated acetanilides were converted into phenanthridine and carbazole derivatives by using Ph3PO and Tf2O or palladium or Cu(OTf)2 catalysts.
