Palate, Kleopas Y.; Yang, Zhongzhen; Whitwood, Adrian C.; Unsworth, William P. published the artcile< Synthesis of medium-ring lactams and macrocyclic peptide mimetics via conjugate addition/ring expansion cascade reactions>, Related Products of 17082-09-6, the main research area is lactam macrocyclic peptide mimetic preparation; primary amine cyclic imide conjugate addition ring expansion.

A novel conjugate addition/ring expansion (CARE) cascade reaction sequence is reported that enables medium-sized ring and macrocyclic bis-lactams to be prepared from primary amines and cyclic imides. The reactions are simple to perform, generally high yielding, and very broad in scope, especially with respect to the primary amine component. CARE reactions can also be performed iteratively, enabling β-peptoid-based macrocyclic peptide mimetics to be ‘grown’ via well controlled, sequential 4-atom ring expansion reactions, with the incorporation of varied functionalized amines during each iteration.

A strategy for DNA-compatible, palladium-catalyzed hydroxycarbonylation of (hetero)aryl halides on DNA-chem. conjugates has been developed. This method generally provided the corresponding carboxylic acids in moderate to very good conversions for (hetero)aryl iodides and bromides, and in poor to moderate conversions for (hetero)aryl chlorides. These conditions were further validated by application within a DNA-encoded chem. library synthesis and subsequent discovery of enriched features from the library in selection experiments against two protein targets.

Jeans, Rebekah J.; Chan, Antony P. Y.; Riley, Laura E.; Taylor, James; Rosair, Georgina M.; Welch, Alan J.; Sivaev, Igor B. published the artcile< Arene-Ruthenium Complexes of 1,1'-Bis(ortho-carborane): Synthesis, Characterization, and Catalysis>, Name: (Hexamethylbenzene)ruthenium(II) dichloride dimer, the main research area is areneruthenium complex ortho carborane preparation catalyst Diels Alder reaction; crystal structure arene ruthenium complex ortho carborane; mol structure arene ruthenium complex ortho carborane.

Deprotonation of 1,1′-bis(ortho-carborane) with BuLi in THF followed by reaction with [RuCl2(p-cymene)]2 affords, in addition to [Ru(κ3-2,2′,3′-{1-(1′-closo-1′,2′-C2B10H10)-closo-1,2-C2B10H10})(p-cymene)] (I), a small amount of a new species, [Ru(κ3-2,2′,11′-{1-(7′-nido-7′,8′-C2B9H11)-closo-1,2-C2B10H10})(p-cymene)] (1a), with two B-agostic B-H⇀Ru bonds, making the bis(carborane) unit a closo-nido-X(C)L2 ligand, a previously unreported bonding mode. Similar species were also formed with arene = benzene (1b), mesitylene (1c), and hexamethylbenzene (1d), although in the last two cases the metallacarborane-carborane species [1-(1′-closo-1′,2′-C2B10H11)-3-(arene)-closo-3,1,2-RuC2B9H10], 2c and 2d, were also isolated. With the bis(ortho-carborane) transfer reagent [Mg(κ2-2,2′-{1-(1′-closo-1′,2′-C2B10H10)-closo-1,2-C2B10H10})(DME)2], the target compounds [Ru(κ3-2,2′,3′-{1-(1′-closo-1′,2′-C2B10H10)-closo-1,2-C2B10H10})(arene)], 4b and 4d, were prepared in reasonable-to-good yields, although for arene = benzene and mesitylene small amounts of the unique paramagnetic species [{Ru(arene)}2(μ-Cl)(μ-κ4-2,2′,3,3′-{1-(1′-closo-1′,2′-C2B10H9)-closo-1,2-C2B10H9})], 3b and 3c, were also formed. In compounds 3, the bis(carborane) acts as a closo-closo-X4(C,C’,B,B’) ligand to the Ru2 unit. In I, 4b, and 4d, the B-agostic B-H⇀Ru bond is readily cleaved by MeCN, affording compounds [Ru(κ2-2,2′-{1-(1′-closo-1′,2′-C2B10H10)-closo-1,2-C2B10H10})(arene)(NCMe)] (5a, 5b, and 5d) and suggesting that I, 4b, and 4d could act as Lewis acid catalysts, which is subsequently shown to be the case for the Diels-Alder cycloaddition reactions between cyclopentadiene and methacrolein, ethylacrolein and E-crotonaldehyde. All new species were characterized by multinuclear NMR spectroscopy and 1a, 1c, 1d, 2c, 2d, 3b, 3c, 4b, 4d, 5a, 5b, and 5d were also characterized crystallog.

We report the discovery of a novel benzylpiperidine derivative with serotonin transporter (SERT) inhibitory activity and 5-HT1A receptor weak partial agonistic activity showing the antidepressant-like effect. The 3-methoxyphenyl group and the phenethyl group of compound 1, which has weak SERT binding activity, but potent 5-HT1A binding activity, were optimized, leading to compound 35 with potent and balanced dual SERT and 5-HT1A binding activity, but also potent CYP2D6 inhibitory activity. Replacement of the methoxy group in the left part of compound 35 with a larger alkoxy group, such as ethoxy, isopropoxy or methoxy-ethoxy group ameliorated CYP2D6 inhibition, giving SMP-304 as a candidate. SMP-304 with serotonin uptake inhibitory activity and 5-HT1A weak partial agonistic activity, which could work as a 5-HT1A antagonist, displayed faster onset of antidepressant-like effect than a representative SSRI paroxetine in an animal model.

Chang, Suae-Chen; Gleicher, Gerald J. published the artcile< Attempt to observe neighboring group participation in hydrogen abstraction from β-(substituted phenyl)-ethyl bromides>, Synthetic Route of 16799-05-6, the main research area is hydrogen abstraction phenethyl bromide; mechanism hydrogen abstraction.

A series of β-(substituted phenyl)-ethyl bromides are reacted with bromotrichloromethane at 70°. Benzylic hydrogen abstraction comprises the only reaction. The exptl. ρ value for this process is -0.83 ± 0.02. A ρ value is calculated to have the range of -0.84 to -0.90. The negligible difference between these two ρ values is indicative of no anchimeric assistance in this reaction by the neighboring bromine atom under the conditions utilized.

Zander, Frank; Finkelmann, Heino published the artcile< State of Order of the Crosslinker in Main-Chain Liquid Crystalline Elastomers>, Related Products of 3964-57-6, the main research area is state order crosslinker main chain liquid crystalline elastomer.

Rigid anisotropic crosslinkers were shown to decrease the nematic order and the transition temperatures of main-chain liquid crystalline elastomers (MCLCEs). In order to look into this phenomenon, the state of order of an anisotropic crosslinker in an MCLCE was studied sep. from that of the matrix. For this purpose, multifunctional perylene derivatives were synthesized and used as a crosslinker and as a reference mesogen probe. Their states of order were measured by their dichroism, and were compared to that of the MCLCE matrix. A systematically lower degree of order was observed for the crosslinker in comparison to the matrix, both when attached to and dissolved in the network.
