Selective Mono Bromination of 1,4-Dihydropyridines
نویسندگان
چکیده مقاله:
2-monobromomethyl 1,4-dihydropyridines is selectively synthesized by bromination of the parent compound by 1.1 equivalents of pyridinium bromide perbromide in dichloromethane/pyridine at -20 °C. The same reagent in dichloromethane at 0 °C produce the 2,6-bis(bromomethyl) 1,4-dihydropyridines.

متن کاملSynthesis of 2-Mono and 2,6-Disubstituted Methyl-1,4-Dihydropyridines
The 2-mono and 2,6-disubstituted methyl-1,4-dihydropyridines were synthesized by reaction of morpholine, thiophenol, 8-hydroxyquinoline, 2-naphthol and 2-mercopto-1-methyl imidazole with the 2-mono bromo and 2,6-dibromo-1,4-dihidropyridines.
متن کاملRuthenium-Catalyzed meta-Selective C—H Bromination
The first example of a transition-metal-catalyzed, meta-selective C-H bromination procedure is reported. In the presence of catalytic [{Ru(p-cymene)Cl2 }2 ], tetrabutylammonium tribromide can be used to functionalize the meta C-H bond of 2-phenylpyridine derivatives, thus affording difficult to access products which are highly predisposed to further derivatization. We demonstrate this utility w...

متن کاملMono- and di-bromo platinum(IV) prodrugs via oxidative bromination: synthesis, characterization, and cytotoxicity.
Platinum(IV)-based anticancer prodrugs have attracted much attention due to their relative inertness under physiological conditions, being activated inside cells, and their capacity for functionalization with a variety of small-molecule or macromolecule moieties. Novel asymmetric platinum(IV) compounds synthesized through expedient and unique methods are desired. Here we utilize N-bromosuccinim...
متن کاملOne‐Pot Synthesis of a bis‐Pocket Corrole through a 14‐fold Bromination Reaction
A one-pot protocol, effecting 14-fold bromination with elemental bromine, has afforded copper β-octabromo-meso-tris(2,6-dibromo-3,5-dimethoxyphenyl)corrole, a new bis-pocket metallocorrole. The Cu complex underwent smooth demetalation under reductive conditions, affording the free corrole ligand, which in turn could be readily complexed to MnIII and AuIII. A single-crystal X-ray structure was o...
