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.

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.

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.

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.

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.
