Investigating the Oxidation Step in the CuCl2-Catalyzed Aerobic Oxidative Coupling Reaction of N-Aryl Tetrahydroisoquinolines

The oxidative coupling of N-aryl tetrahydroisoquinolines with nucleophiles has inspired the development of novel C-H functionalization reactions as well as mechanistic studies. Here, we investigate the oxidation step that forms iminium ions as key intermediates in the method using CuCl2 as the catalyst and oxygen as the terminal oxidant. A strong electronic effect of substituents in the N-aryl ring was found by synthetic studies and a Hammett plot analysis, supporting initial electron transfer from the amine to Cu(II). The importance of the mechanism of oxidation on the substrate scope with differently substituted tetrahydroisoquinolines is discussed.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 3340-78-1, help many people in the next few years.Formula: C15H15N

The 3,7-diazabicyclo[3.3.1]nonane scaffold for subtype selective nicotinic acetylcholine receptor ligands. Part 2: Carboxamide derivatives with different spacer motifs

3,7-Diazabicyclo[3.3.1]nonane (bispidine) based nicotinic acetylcholine receptor (nAChR) ligands have been synthesized and evaluated for nAChRs interaction. Diverse spacer motifs were incorporated between the hydrogen bond acceptor (HBA) part and a variety of substituted (hetero)aryl moieties. Bispidine carboxamides bearing spacer motifs often showed high affinity in the low nanomolar range and selectivity for the alpha4beta2* nAChR. Compounds 15, 25, and 47 with Ki values of about 1 nM displayed the highest affinities for alpha4beta2* nAChR. All evaluated compounds are partial agonists or antagonists at alpha4beta2*, with reduced or no effects on alpha3beta4* with the exception of compound 15 (agonist), and reduced or no effect at alpha7 and muscle subtypes.

Noncompetitive NMDA Antagonists: A novel synthesis of 1-phenyltetrahydro-3-benzazepines

The key step in the synthesis of the pharmacologically interesting l-phenyltetrahydro-3-benzazepine skeleton is the Michael addition of (2-lithiophenyl)acetaldehyde acetals, which are generated in situ upon treatment of the bromo acetals 5a,b with n-butyllithium, to beta-nitrostyrene (6). The reductive ring closure of the nitro acetals 7a,b succeeded with zinc dust and hydrochloric acid to give the 3-benzazepines 11a,b in good yields. The unsubstituted 3-benzazepine 11a showed a considerable affinity for the phencyclidine binding site of the NMDA receptor (K(i) = 6.41 muM), whereas donor substituents in the aryl moiety (11b,c) reduce the affinity for the NMDA receptor.

Non-peptide glycoprotein IIb/IIIa antagonists. 11. Design and in vivo evaluation of 3,4-dihydro-1(1H)-isoquinolinone-based antagonists and ethyl ester prodrugs

The structure-activity relationship of a series of orally active glycoprotein IIb/IIIa antagonists containing a nitrogen heterocycle grafted onto a 3,4-dihydro-1(1H)-isoquinolinone core is described. These compounds are structurally novel analogs of the progenitor compound 1 (L-734,217, [[3(R)-[2-(piperidin-4-yl)ethyl]-2-oxopiperidinyl]acetyl]-3(R)-methy-beta- alanine) in which the lactam chiral center has been removed. The 4- piperazinyl- and 4-piperidinyl-substituted 3,4-dihydro-1(1H)-isoquinolinones were found to be optimal for in vitro potency. In addition, substitution at the 3-position of the beta-amino acid enhanced potency with the 3-pyridyl and 3-ethynyl analogs being the most potent prepared. Attempts to improve the in vivo profile of these compounds focused on modification of the physical properties. Ester prodrugs were prepared to increase the lipophilicity and remove the zwitterionic nature of the antagonists. The prodrug approach, coupled with the arylpiperazine terminus (pK(a) = ~9.0), afforded moderately basic and relatively nonpolar compounds. The acid N-[[7-(piperazin-1-yl)- 3,4-dihydre-1(1H)-oxoisoquinolin-2-yl]acetyl]-3(S)-ethynyl-beta-alanine, 6d (L- 767,679), is a potent fibrinogen receptor antagonist able to inhibit the ADP- induced aggregation of human gel-filtered platelets with an IC50 of 12 nM. Although 6d is orally active based on the results of an ex vivo dog assay at 0.3 mg/kg, the ethyl ester prodrug of this compound, 19 (L-767,685), is better absorbed at this dose than 6d. Upon oral dosing, the ester 19 is converted to 6d in vivo in dog with an estimated oral systemic availability of >17% (0-8 h, AUC(19po)/AUC(6div)). In addition, studies in monkey at an oral dose of 1 mg/kg show that 19 affects the complete inhibition of the ex vivo platelet aggregation in response to ADP between 2 and 8 h postdose with the level of inhibition remaining at 40% at 12 h postdose. This level of activity was superior to that observed for 6d and 1 at the same dose. Using ex vivo ADP-induced aggregation data from rhesus monkey (n = 2, 0-8 h using the AUC(19po)/AUC(6div)), the estimated systemic oral availability of 6d when dosed as 19 is 32%.

Highly stable and porous cross-linked polymers for efficient photocatalysis

Porous cross-linked polymers (PCPs) with phosphorescent [Ru(bpy) 3]2+ and [Ir(ppy)2(bpy)]+ building blocks were obtained via octacarbonyldicobalt (Co2(CO) 8)-catalyzed alkyne trimerization reactions. The resultant Ru- and Ir-PCPs exhibited high porosity with specific surface areas of 1348 and 1547 m2/g, respectively. They are thermally stable at up to 350 C in air and do not dissolve or decompose in all solvents tested, including concentrated hydrochloric acid. The photoactive PCPs were shown to be highly effective, recyclable, and reusable heterogeneous photocatalysts for aza-Henry reactions, alpha-arylation of bromomalonate, and oxyamination of an aldehyde, with catalytic activities comparable to those of the homogeneous [Ru(bpy) 3]2+ and [Ir(ppy)2(bpy)]+ photocatalysts. This work highlights the potential of developing photoactive PCPs as highly stable, molecularly tunable, and recyclable and reusable heterogeneous photocatalysts for a variety of important organic transformations.

Library Construction and Biological Evaluation of Enmein-Type Diterpenoid Analogues as Potential Anticancer Agents

A library of promising enmein-type 14-O-diterpenoid derivatives was constructed from a commercially available kaurene-type oridonin by practical and efficient synthetic methods. These synthetic derivatives were evaluated for their antiproliferative activities against a set of four human cancer cell lines. The IC50 values are similar to or improved over those of the parent molecule and paclitaxel, the latter of which was used as a positive control. Compound 29 was further investigated for its apoptotic properties against human hepatocarcinoma Bel-7402 cells to better understand its mode of action. Moreover, compound 29 was shown to have potent antitumor activity invivo in studies with a murine model of gastric cancer (MGC-803 mice). These results warrant further preclinical investigations of these diterpenoid-based analogues as potential novel anticancer chemotherapeutics. Dosing with diterpenoids: A synthetic library of enmein-type diterpenoid derivatives with potent antitumor activities was constructed by using commercially available starting materials. The analogue shown here exhibits potent invitro and invivo activities and suitable chemical properties similar to or exceeding those of the parent compound, warranting further preclinical investigations for potential diterpenoid-based anticancer agents.
