Iridium-Catalyzed Annulation Reactions of Thiophenes with Carboxylic Acids: Direct Evidence for a Heck-type Pathway

The functionalization of thiophenes is a fundamental and important reaction. Herein, we disclose iridium-catalyzed one-pot annulation reactions of (benzo)thiophenes with (hetero)aromatic or alpha,beta-unsaturated carboxylic acids, which afford thiophene-fused coumarin-type frameworks. Dearomatization reactions of 2-substituted thiophenes with alpha,beta-unsaturated carboxylic acids deliver various thiophene-containing spirocyclic products. The occurrence of two interconnected reactions provides direct evidence for a Heck-type pathway. The mechanistic scenario described herein is distinctly different from the SEAr and concerted metalation?protodemetalation (CMD) pathways encountered in the well-described oxidative C?H/C?H cross-coupling reactions of thiophenes with other heteroarenes.

Photoinduced Miyaura Borylation by a Rare-Earth-Metal Photoreductant: The Hexachlorocerate(III) Anion

The first photoinduced carbon(sp2)?heteroatom bond forming reaction by a rare-earth-metal photoreductant, a Miyaura borylation, has been achieved. This simple, scalable, and novel borylation method that makes use of the hexachlorocerate(III) anion ([CeIIICl6]3?, derived from CeCl3) has a broad substrate scope and functional-group tolerance and can be conducted at room temperature. Combined with Suzuki?Miyaura cross-coupling, the method is applicable to the synthesis of various biaryl products, including through the use of aryl chloride substrates.

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.

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.

The reaction flask was degassed threetimes with argon and anhyd tert-pentyl alcohol (3.0 mL) was addedusing a syringe. Then 1-bromo-4-(tert-butyl)benzene (2b; 64 mg, 0.3mmol) was added with a syringe. Note that the aryl bromide in a solidform was added to the reaction flask prior to Cs2CO3. The reactionwas heated at 90 C with stirring for about 4 h, then it was cooled tor.t., and filtered through a short pad of neutral alumina with EtOAc(25 mL) as eluent. Solvent was then removed in vacuo to leave a crudemixture, which was purified by silica gel column chromatography(eluent: PE); yellow solid (82 mg, 91%).
