Diazines VII. A new synthetic route to the pyridazine antidepressant, minaprine using directed ortho metalation and Suzuki cross coupling reactions

A new synthetic route has been developed for minaprine.The synthesis is based upon two reactions recently studied on pyridazine: metalation and cross coupling with transition metals.Some different routes have been tested starting from 3,6-dichloropyridazine.The best results were obtained by coupling phenylboronic acid with 3-chloro-6-methoxypyridazine then by metalating 3-methoxy-6-phenylpyridazine and reacting the lithio derivatives with methyl iodide. 3-Methoxy-4-methyl-6-phenylpyridazine was obtained.After hydrolysis of the ether moiety, chlorination and substitution by the amine, minaprine was obtained with an overall yield of 36percent.Keywords – pyridazine / metalation / cross-coupling

Octahydropyrrolo[3,4-c]pyrrole: A diamine scaffold for construction of either alpha4beta2 or alpha7-selective nicotinic acetylcholine receptor (nAChR) ligands. Substitutions that switch subtype selectivity

A series of 5-(pyridine-3-yl)octahydropyrrolo[3,4-c]pyrroles have been prepared that exhibit high affinity to alpha4beta2 and/or alpha7 nicotinic acetylcholine receptors (nAChRs). Simple substitution patterns have been identified that allow construction of ligands that are highly selective for either nAChR subtype. The effects of substitution on subtype selectivity provide some insight into the differences in the ligand binding domains of the alpha4beta2 and R7 receptors, especially in regions removed from the cation binding pocket.

Desymmetrization of dichloroazaheterocycles

3,6-Dichloropyridizine 1a was converted in good yield into its mono-iodo derivative 1b when treated with a mixture of hydriodic acid and sodium iodide. Pure samples of the mono-iodo derivatives 2b, 3b and 4b could not be obtained from their corresponding dichlorinated precursors with these reagents. Compounds 1b and 4b underwent palladium catalysed Suzuki, Sonogashira and other coupling reactions.

Synthetic approaches to polypyridyl bridging ligands with proximal multidentate binding sites

A series of 12 bridging ligands was prepared. These ligands include a central linker appended to two 1,8-naphthyrid-2-yl or two 1,10-phenanthrolin-2- yl units. The linkers include pyridazin-3,6-diyl, 1,8-naphthyrid-2,7-diyl, 2,2?-bipyrid-6,6?-diyl, 1,10-phenanthrolin-2,9-diyl, 1,2-di(2?-pyrid-6?-yl)ethyne, and 3,6-di(2?-pyrid-6?-yl) pyridazine. The ligands were synthesized from the diacetyl derivative of the central linker by a Friedlaender condensation with either 2-aminonicotinaldehyde or 8-amino-7-quinolinecarbaldehyde. The precursor diacetyl derivatives were, in turn, prepared by pathways involving Stille and Sonogashira couplings. Examination of the electronic absorption spectra of the bridging ligands shows the strongest correlation to be between pairs of ligands having the same central linker. Complexation studies will follow.

AG+ Ion-selective lariat ethers: high pressure sunthesis and cation recognition properties

A new seies of lariat ethers have been prepared by a high pressure SNAr reaction, in which various heteroaromatics are directly connected to the nitrogens of 12-, 15- and 18-membered aza-crown ethers.Liquid membrane transport studies demonstrated that lariat ethers having thiazole, oxazole, pyrazine and pyridazine rings on their sidearms exhibited excellent Ag+ ion selectivity. 13C NMR binding experiments revealed that these lariat ethers selectively formed encapsulated Ag+ complexes in a different fashion from that of double armed crown ethers.Cooperative action between the heteroaromatic sidearm and tha aze-crown ring afforded unique cation recognition.

The synthesis and chemical reactivity of 3-chloro-6-(2- pyrrolyl)pyridazine

3,6-Dichloropyridazine and 1-alkyl-3,6-dichloropyridazinium cations react with pyrrolylmagnesium bromide to produce 3-chloro-6-(2- pyrrolyl)pyridazine. Further reaction with other nucleophiles is slow, but is enhanced by quaternisation of the 2-N atom. 3,6-Di(2-pyrrolyl)pyridazine could not be obtained by this route.

Grafting of [CpMo(CO)3]-Na+ on 3,6-dichloro-pyridazine modified mesoporous MCM-41 and MCM-48 molecular sieves

MCM-41/48 samples are hydrothermally synthesized and employed for fixing a modified pyridazine ligand and grafting a CpMo(CO)3-moiety through the reaction of the chlorine ligand of the surface fixed pyridazine with [CpMo(CO)3]-Na+. The grafted materials are characterized by analytical and spectroscopic techniques including XRD, FT-IR, BET, TEM, 29Si CP MAS NMR and elemental analysis. The heterogenized materials are applied for the catalytic epoxidation of cyclooctene. XRD and N2 adsorption/desorption analysis of the parent MCM-41, MCM-48 and of the grafted samples are providing strong evidence that the mesoporous structure of the support retains long range ordering throughout the grafting process and that the channels remain accessible. Elemental analyses (EA) indicate the presence of 1.7-2.2 wt. % of Mo in the grafted samples. FT-IR and 29Si MAS NMR spectra of the grafted samples show a decrease in the relative intensity of the silanol (Si-OH) band, indicating that the surface hydroxyl groups have been partially used for the grafting. New bands around 2016 and 1956 cm-1 can be assigned to terminal carbonyl (CO) group vibrations of the grafted CpMo(CO)3-moiety. Furthermore, the hydrogenised compounds are found to be promising for the epoxidation of olefines.
