A Pd-catalyzed Miyaura borylation of 3-bromo-2,1-borazaronaphthalenes is reported. This method allows the formation of umpolung reagents for subsequent Pd-mediated cross-coupling. Coupling of this nucleophilic partner with a variety of commercially available aryl- and heteroaryl halides allows facile and rapid diversification of these cores.

A new method of Sonogashira coupling reactions between diorganyl tellurides and terminal alkynes is reported. The coupling reactions are performed using Pd(dppf)Cl2 as a catalyst, CuI as a co-catalyst in the presence of K2CO3 in DMSO. The reactions are carried out at room temperature and completed within 2 h when phenyl acetylene is used as a terminal alkyne. For aliphatic terminal alkynes, such as 1-hexyne and 1-octyne, an elevated temperature and longer reaction time are needed for the completion of the reactions. This process results in good yields of Sonogashira coupling products which is applicable for diaryl, divinyl and dialkynyl tellurides but not applicable for dialkyl tellurides.

Condensation of [Mn2(CO)8(mu-PPh2)]- with Pd(II) assisted by Ag(I) leads to cluster disproportionation, viz. Mn2Pd2Ag(mu-Cl)(mu-PPh2)2(mu-d ppm)(CO)8 and MnPd(mu-PPh2)(CO)4(eta2-P-P) (P-P = dppm, dppe, dppf). The former shows a distorted bow-tie structure with two heterometallic triangles {AgPdMn} sharing an Ag center. The unexpected phosphide migration across different metals holds the key to the cleavage and formation of metal-metal bonds. The bimetallic complexes are stabilized by all common diphosphines whereas the polymetallic structure is isolated only when supported by dppm. The latter shows three different types of heterometal-metal bonds Ag-Mn (2.6938(4) A), Ag-Pd (2.7637(1) A) and Mn-Pd (2.8183(9) A) (average values).

The lipid kinase phosphoinositide 3-kinase gamma (PI3Kgamma) has attracted attention as a potential target to treat a variety of autoimmune disorders, including multiple sclerosis, due to its role in immune modulation and microglial activation. By minimizing the number of hydrogen bond donors while targeting a previously uncovered selectivity pocket adjacent to the ATP binding site of PI3Kgamma, we discovered a series of azaisoindolinones as selective, brain penetrant inhibitors of PI3Kgamma. This ultimately led to the discovery of 16, an orally bioavailable compound that showed efficacy in murine experimental autoimmune encephalomyelitis (EAE), a preclinical model of multiple sclerosis.

A new heterometallic dyad composed of a zinc porphyrin linked by bisethynyl quaterthiophene to a gold porphyrin was synthesized according to a stepwise modular approach. The latter dyad and the parent reference compounds (porphyrin-ethynylquaterthiophene) were characterized by electrochemistry, spectroelectrochemistry, and femtosecond transient absorption spectrocopy. We showed that light excitation of the zinc or the gold porphyrin induces a very fast and quantitative charge separation over a distance of 25 A which occurs through a superexchange mechanism. The lifetime of the charge-separated state is 3.3 ns in toluene and 100 ps in dichloromethane, and it recombines to the ground state in both solvents.

Novel treatments for bipolar disorder with improved efficacy and broader spectrum of activity are urgently needed. Glycogen synthase kinase 3beta (GSK-3beta) has been suggested to be a key player in the pathophysiology of bipolar disorder. A series of novel GSK-3beta inhibitors having the common N-[(1-alkylpiperidin-4-yl)methyl]-1H-indazole-3-carboxamide scaffold were prepared taking advantage of an X-ray cocrystal structure of compound 5 with GSK-3beta. We probed different substitutions at the indazole 5-position and at the piperidine-nitrogen to obtain potent ATP-competitive GSK-3beta inhibitors with good cell activity. Among the compounds assessed in the in vivo PK experiments, 14i showed, after i.p. dosing, encouraging plasma PK profile and brain exposure, as well as efficacy in a mouse model of mania. Compound 14i was selected for further in vitro/in vivo pharmacological evaluation, in order to elucidate the use of ATP-competitive GSK-3beta inhibitors as new tools in the development of new treatments for mood disorders.

The palladium catalysed Miyaura cross-coupling reactions of 4?-(4-bromophenyl)-2,2?:6?,2?-terpyridine (tpy-phi-Br) and 4?-bromo-2,2?:6?,2?-terpyridine (tpy-Br) with bis(neopentyl glycolato)diboron (B2neo2 lead to the first reported examples of boronate ester-substituted terpyridine ligands, L1 and L2. Ligand L1, which incorporates a benzene ring between the terpyridine group and the boron, reacts with transition metals such as iron and ruthenium to generate complexes containing the analogous boronic acid-substituted terpyridine L3. The heteroleptic complex [Ru(ttpy)L3]2+ has also been prepared by an analogous cross-coupling reaction of the bromo complex [Ru(ttpy)(tpy-phi-Br)]2+ with B2neo2 (ttpy =4?-tolyl-2,2?:6?,2?-terpyridine). The structurally related complex [Ru(ttpy)L4]2+ (L4 = terpyridine-4?-boronic acid) could not be prepared, either directly from L2 or from [Ru(ttpy)(tpy-Br)]2+, apparently due to competitive hydrodeboration and solvolysis. The complex [Ru(ttpy)L3]2+ reacts with aryl halides under standard palladium-catalysed Suzuki-Miyaura cross-coupling conditions to generate more elaborate 4?-aryl-substituted terpyridyl complexes. Cross-coupling has also been achieved by reaction of [Ru(ttpy)(tpy-Br)]2+ with an arylboronic acid. The photophysical properties of [Ru(ttpy)L3]2+ are shown to be largely typical of ruthenium bis-terpyridyl complexes.
