A novel approach to the selective preparation of 4-bromoindoles was developed via Pd(OAc)2/racBINAP catalytic reactions. A variety of 4,6-dibromoindoles were transformed to 4-bromoindoles with high regioselectivity. This methodology, along with C-N and C-O bond-forming reactions developed in ...
Reaction conditions: amines (0.2 mmol), arylsulfonyl chlorides (0.6 mmol), K2CO3 (0.6 mmol), Pd(OAc)2 (0.01 mmol, 5 mol%), ligand (PPh3, 0.04 mmol or rac-BINAP, 0.02 mmol), dry 1,4-dioxane (0.1 M), room temperature, irradiation with 34 W blue ...
Using Pd(OAc)2 (10 μmol, 5 mol%) as the catalyst. e Using DMF (4.0 mL) as the solvent. f Using DMSO (4.0 mL) as the solvent. g Using (S)-F (20 μmol, 10 mol%) as the ligand. h The reaction was carried out at 130°C. i The reaction was carried out at 160°C. Sc...
(entries 2 and 3). The use of ligand Cy-XantphosL2, Xantphos, DPEphos orrac-BINAP instead ofL1resulted in trace product (entries 4–5). Using THF or toluene as the solvent showed no strong influence on this reaction (entry 6). Other palladium catalysts such as Pd(PPh3)2Cl2, Pd(PPh3...
Palladium catalysed enamine synthesis from vinyl triflates.Vinyl triflates can be converted into the corresponding enamines by treatment with a secondary amine, Cs2CO3 and a catalyst generated from Pd(OAc)2 and rac-BINAP.[Copyright &y& Elsevier]Willis...
mol% of Pd(dba)2, rac-BINAP and BINOL phosphoric acid as catalytic mixture. This procedure allows the in situ synthesis of 3-allyl-2-oxindole by adding Triton B to the reaction mixture. The deacylative allylation of 3-acetyl-3-methyl-2-oxindoles with allylic alcohols is carried out with...
Palladium-catalyzed intramolecular 伪-arylations of sulfoximines bearing 2-bromobenzyl and 2-bromobenzoyl groups at the imine nitrogen result in the formation of heterocycles in moderate to good yields. A catalytic protocol based on the use Pd(OAc) 2 as metal source, rac-BINAP as ligand and K ...
The palladium-catalyzed cyclization of N-(2-bromobenzyl)- and N-(2-bromobenzoyl)-sulfoximines affords six-membered heterocycles in moderate to good yield. In both cases, the 伪-arylations of the sulfoximine methyl groups are catalyzed by combination of Pd(OAc)2 and rac-BINAP in the presence ...
