Ligandless copper-catalyzed coupling of heteroaryl bromides with gaseous ammonia

A range of different N- and S-containing heterocyclic bromides can be efficiently coupled with gaseous ammonia in the presence of copper(II) acetylacetonate [Cu(acac)2] as catalyst and in the absence of additional ligands. Unstable aminothiophenes and aminobenzothiophenes can be further reacted in situ to afford functionalized derivatives. Copyright

Transition-Metal-Free Synthesis of Heterobiaryls through 1,2-Migration of Boronate Complex

The synthesis of a diverse range of heterobiaryls has been achieved by a transition-metal-free sp2?sp2 cross-coupling strategy using lithiated heterocycle, aryl or heteroaryl boronic ester and an electrophilic halogen source. The construction of heterobiaryls was carried out through electrophilic activation of the aryl?heteroaryl boronate complex, which triggered 1,2-migration from boron to the carbon atom. Subsequent oxidation of the intermediate boronic ester afforded heterobiaryls in good yield. A comprehensive 11B NMR study has been conducted to support the mechanism. The cross coupling between two nucleophilic cross coupling partners without transition metals reveals a reliable manifold to procure heterobiaryls in good yields. Various heterocycles like furan, thiophene, benzofuran, benzothiophene, and indole are well tolerated. Finally, we have successfully demonstrated the gram scale synthesis of the intermediates for an anticancer drug and OLED material using our methodology.

Discovery of the alpha7 nicotinic acetylcholine receptor agonists. (R)-3?-(5-chlorothiophen-2-yl)spiro-1-azabicyclo[2.2.2]octane-3, 5?-[1?,3?]-oxazolidin-2?-one as a novel, potent, selective, and orally bioavailable ligand

Recent advances in molecular biology suggest that neuronal nicotinic acetylcholine receptors play important roles in the central nervous system (CNS). Of these receptors, the alpha7 group has recently attracted interest for its CNS-related actions and is looked to as a potential new class of pharmacological targets for cognition, schizophrenia, sensory gating, and anxiety. In the course of a research program aimed at the discovery of alpha7 receptor agonists with high affinity, subtype selectivity, and good pharmacokinetic profile, we discovered (R)-3?-(5-chlorothiophen-2-yl) spiro-1-azabicyclo[2.2.2]octane-3,5?-[1?,3?] oxazolidin-2?-one (25). Compound 25 has potent binding affinity (K i = 9 nmol/L) and good selectivity toward the other nicotinic subtypes (alpha4beta2 and alpha1beta2gammadelta) and has been found in pharmacokinetic evaluation to have good oral bioavailability and brain permeability.

Effects of pi-extension on pyrrole hemithioindigo photoswitches

The most red-shifted hemithioindigo photoswitches have been identified through systematic introduction of aryl units to a parent pyrrole hemithioindigo photoswitch. Increasing the size of the 5?-aryl substituent is ineffective at producing further redshifted chromophores. A second generation of 3?,5?-diarylated photoswitches which possess increased tunability is reported. Experimental and computational evidence indicates the 4? position is electronically isolated from the bulk of the conjugated system.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of Benzo[b]thiophen-3(2H)-one, you can also check out more blogs about130-03-0

Ligand cooperation in the formal hydrogenation of N2O using a PCsp2P iridium pincer complex

A new PCcarbeneP pincer ligand with 2,3-benzo[b]thiophene linkers connecting the flanking dialkyl phosphine donors to the central carbene can be attached to Ir(I). The chloro derivative reacts with N2O with loss of N2 to form an iridaepoxide species by addition of an oxygen atom to the Ir=C linkage. This compound reacts with H2 to afford the oxidative addition product, in which the hydride ligands are trans to the Ir-O bond. Heating this dihydride results in slow release of H2O; kinetic and spectroscopic studies show that conversion of the dihydride to its isomer, in which the hydrides are cis to the Ir-O bond, is required for H2O elimination to take place. Together, these reactions constitute the stoichiometric conversion of N2O and H2 to N2 and H2O; further mechanistic studies suggest ways to make the system catalytic.

Design and synthesis of 4-heteroaryl 1,2,3,4-tetrahydroisoquinolines as triple reuptake inhibitors

(Chemical Equation Presented) A series of 4-bicyclic heteroaryl 1,2,3,4-tetrahydroisoquinoline inhibitors of the serotonin transporter (SERT), norepinephrine transporter (NET), and dopamine transporter (DAT) was discovered. The synthesis and structure-activity relationship (SAR) of these triple reuptake inhibitors (TRIs) will be discussed. Compound 10i (AMR-2), a very potent inhibitor of SERT, NET, and DAT, showed efficacy in the rat forced-swim and mouse tail suspension models with minimum e ffective doses of 0.3 and 1 mg/kg (po), respectively. At efficacious doses in these assays, 10i exhibited substantial occupancy levels at the three transporters in both rat and mouse brain. The study of the metabolism of 10i revealed the formation of a significant active metabolite, compound 13.

Cope Rearrangements in the Benzothiophene Series

The inability to observe Cope rearrangement products at elevated temperatures for diethyl alpha-allyl-2-naphthalenemalonate (1) and diethyl alpha-allyl-9-phenanthrenemalonate (2) does not extend to the analogous systems resulting from replacement of the aromatic units by 2- and 3-benzothiophene nuclei.Thermal rearrangement of diethyl alpha-allyl-3-benzothiophenemalonate (5) at 215-255 deg C for 11 h produces the expected Cope rearrangement product diethyl 2-allyl-3-benzothiophenemalonate (10) (8percent) accompanied by trans- and cis-ethyl 2,3-dihydro-1-(ethoxycarbonyl)-1H-benzocyclopentathiophene-2-acetate (9a) (10percent) and (9b) (5percent), respectively.The structure elucidation of 10, 9a, and 9b was done by spectroscopy.The attempted structure verification of 10 by an independent route gave diethyl 2-(1-propenyl)-3-benzothiophenemalonate (12) which when heated at 230-240 deg C for 18 h gave 1-carbethoxy-2-hydroxy-3-methyldibenzothiophene (16) as a major product.Similar results were observed with 2-substituted analogues of 5, both diethyl 3-allyl-2-benzothiophenemalonate (24) and ethyl 1,2-dihydro-3-(ethoxycarbonyl)-3H-benzocyclopentathiophene-2-acetate (25) being formed.In this case the structure of 24 was verified by synthesis.An extension of this involved a study of thermal rearrangement of analogous compound ethyl alpha-allyl-alpha-cyano-3-benzothiopheneacetate (30).Thermal rearrangement of 30 at 235-245 deg C for 8 h gave the expected Cope rearrangement product ethyl alpha-cyano-2-allyl-3-benzothiopheneacetate (32) (6percent) along with an unexpected diastereomeric mixture of 1-cyano-1-(ethoxycarbonyl)-2-methyl-2,3-dihydro-1H-benzocyclopentathiophenes (33) (18percent).Speculative mechanistic considerations are offered regarding the mode of transformation of 12 to 16 and 32 to 33.
