Ir(III)-Catalyzed Oxidative Annulation of Phenylglyoxylic Acids with Benzo[ b]thiophenes

An Ir(III)-catalyzed oxidative annulation of phenylglyoxylic acids with benzo[b]thiophenes for the construction of benzothieno[3,2-c][2]benzopyranones in one step is disclosed. Three C-H cleavages and C-C/C-O bond formations are involved in this reaction. This protocol features a relatively broad substrate scope, good functional group tolerance, good regioselectivities, mild reaction conditions, and scale-up synthesis.

Evidence for an Important 13C NMR Shielding Effect for Carbon Atoms Bearing a Heavy Chalcogen Substituent

An important 13C NMR shielding effect on carbons bearing a heavy chalcogen is demonstrated.This effect is parallel to that induced by iodine, but to a lesser extent.For acyclic compounds and for partially saturated heterocycles, there is an excellent linear correlation between the 13C chemical shifts of carbons bearing a chalcogen and carbons bearing a halogen atom in the corresponding compound.The linearity of the relationship is less satisfactory with heteroaromatic compounds.

Palladium-Catalyzed N-Arylation of Iminodibenzyls and Iminostilbenes with Aryl- and Heteroaryl Halides

Compounds containing the iminodibenzyl and iminostilbene ring systems are prevalent in medicinal targets and functional materials. Herein, we report palladium-catalyzed conditions for the N-arylation of these ring systems. This protocol could be applied to a variety of (hetero)aryl chloride and bromide substrates, including ones, which are sterically hindered or those containing a variety of functional groups. Use of the fourth-generation palladacycle precatalyst gave good to excellent yields by using low palladium-catalyst loadings (0.1 to 1 mol %).

Thermolysis of Thiophenedicarboxylic Acid Anhydrides as a Route to Five-Membered Hetarynes

Flow vacuum thermolysis (FVT) of the anhydrides of thiophene-2,3- (5) and -3,4-dicarboxylic acid (6) and of thianaphthene-2,3-dicarboxylic acid (7) in the presence of thiophene, 1,3-cyclohexadiene, or benzene gave thianthrene (15a), presumably by aromatization of an intermadiate Diels-Alder adduct of the diene traps and the aryne 2,3-didehydrothiophene (8).A similar rationale explains the formation of dibenzothiophene from 7 and thiophene, the four monomethylthianaphthenes 22-25 from 5 and cyclopentadiene, 5,6-dimethylthianaphthene (15f) from 5 and 2,3-dimethylbutadiene, and a mixture of hydroxythianaphthenes (15d) from 5 and furan.The latter reaction also produces a mixture of isomeric cyclopentanothiophenes (19) which probably arise by decarbonylation of 15d.An FVT reaction of 5 with propyne as the trap gave a mixture of allenyl-(28) and propynylthiophenes 29 which probably arise by an ene reaction of the trap and the aryne 8.Decomposition of the anhydrides 5 and 6 in molten anthracene led only to Friedel-Crafts products such as thienylanthracenes 33 and quinones 34 from 5 and 39 and 40 from 6.The diene reactivity of thiophene 13a in the gas phase was demonstrated by the formation of naphthalene from its reaction with benzyne generated from the thermolysis of indanetrione and by the formation of indene from 13a plus cyclopentadiene.Possible, but improbable, interpretations of the FVT results without invoking a five-membered hetaryne intermediate are considered.

DPS-2: A Novel Dual MEK/ERK and PI3K/AKT Pathway Inhibitor with Powerful Ex Vivo and In Vivo Anticancer Properties

Development of novel bioactive compounds against KRAS and/or BRAF mutant colorectal cancer (CRC)is currently an urgent need in oncology. In addition, single or multitarget kinase inhibitors against MEK/ERK and PI3K/AKT pathways are of potential therapeutic advantage. A new compound based on the benzothiophene nucleus was synthesized, based on previous important outcomes on other pharmaceutical preparations, to be tested as potential anticancer agent. Treatments by 2-5 muM DPS-2 of several CRC and melanoma cell lines bearing either BRAF or KRAS mutations have shown a remarkable effect on cell viability in 2D and 3D cultures. More detailed analysis has shown that DPS-2 can kill cancer cells by apoptosis, reducing at the same time their autophagy properties. After testing activities of several signaling pathways, the compound was found to have a dual inhibition of two major proliferative/survival pathways, MEK/ERK and PI3K/AKT, in both CRC and melanoma, thus providing a mechanistic evidence for its potent anticancer activity. Antitumor activity of DPS-2 was further validated in vivo, as DPS-2 treatment of mouse xenografts of Colo-205 colorectal cancer cells remarkably reduced their tumor formation properties. Our findings suggest that DPS-2 has significant anti-KRAS/ anti-BRAF mutant CRC activity in preclinical models, potentially providing a novel treatment strategy for these difficult-to-treat tumors, which needs to be further exploited.

Palladium-catalyzed hydroxylation of aryl and heteroaryl halides enabled by the use of a palladacycle precatalyst

A method for the hydroxylation of aryl and heteroaryl halides, promoted by a catalyst based on a biarylphosphine ligand tBuBrettPhos (L5) and its corresponding palladium precatalyst (1), is described. The reactions allow the cross-coupling of both potassium and cesium hydroxides with (hetero)aryl halides to afford a variety of phenols and hydroxylated heteroarenes in high to excellent yield.

Advances toward new antidepressants beyond SSRIs: 1-aryloxy-3- piperidinylpropan-2-ols with dual 5-HT1A receptor antagonism/SSRI activities. Part 4

A series of 1-(1H-indol-4-yloxy)-3-(4-arylpiperidinyl)propan-2-ols possessing potent dual 5-HT1A receptor antagonism and serotonin reuptake inhibition was discovered. The fused aryl ring moiety contributed to the robust dual activities irrespective of the regiochemistry associated with its connectivity to the piperidine central ring.
