Regioselective functionalization of 2,2?-bipyridine and transformations into unsymmetric ligands for coordination chemistry

Novel synthetic strategies for a series of unsymmetrically substituted 2,2?-bipyridines have been developed. These bipyridines have found use in some novel homoleptic and heteroleptic ruthenium(II) complexes. Two methods for regiochemical control of nucleophilic addition to bpy have been explored: (i) mono N-oxidation followed by cyanation and subsequent hydrolysis gave 6-carboxy-2,2?-bipyridine (4); (ii) mono N-methylation followed by the conversion into 6-bromo-2,2?-bipyridine (12) and subsequent nucleophilic addition of lithioacetonitrile followed by hydrolysis of 6-cyanomethyl-2,2?-bipyridine (8) gave the homologous 2,2?-bipyridine-6-acetic acid (9). An established method of regioselective mono-ring alkylation of bpy using methyllithium yielded 6-methyl-2,2?-bipyridine (14), and the generation of the anion of 14 and subsequent addition to a chloromethyl oxazoline was applied to synthesize a second homologue, methyl 2,2?-bipyridine-6-propanoate (16). Structural determinations using 1H, 13C and 2D NMR spectroscopy permitted complete assignments of all signals in the 1H NMR spectra. Acta Chemica Scandinavica 1998.

Modular Synthesis of 4-aryl- and 4-amino-substituted benzene C-2?-Deoxyribonucleosides

A modular methodology for the syntheses of various 4-substituted-phenyl C-2?-deoxyribonucleosides has been developed. Coupling of toluoylated halogenose 1 with 4-bromophenylmagnesium bromide afforded the desired bis(toluoyl)-protected 1beta-(4-bromophenyl)-1,2-dideoxyribofuranose 2a, which was deprotected under Zemplen conditions to give the unprotected 1beta-(4-bromophenyl)-1,2-dideoxyribofuranosc 3, and reprotected to give the bis(tert-butyldimethylsilyl)-protected 1beta-(4-bromophenyl)-1,2- dideoxyribofuranose 4. Alternatively, addition of 1-lithio-4-bromobenzene on tert-butyldimethylsilyl-protected lactone 5, followed by reduction of the hemiketal 6, also gave bis(tert-butyldimethylsilyl)-protected bromophenyl nucleoside 4. Intermediates 2a and 4 were then subjected to a series of palladium-catalyzed cross-coupling reactions, aminations, and C-H activation to give 1beta-[4-(aryl-, alkyl-, or amino)phenyl]-1,2-dideoxyribofuranoses 8a-n after deprotection. Finally, other types of 4-arylphenyl C-nucleosides 8o-u were prepared directly by aqueous-phase Suzuki cross-coupling reactions of unprotected 3 with boronic acids under microwave irradiation.
