Redox-Annulations of Cyclic Amines with 2-(2-Oxoethyl)malonates

Amines such as 1,2,3,4-tetrahydroisoquinoline undergo redox-neutral annulations with 2-(2-oxoethyl)malonates in the presence of catalytic amounts of benzoic acid. These reactions install a fully saturated five-membered ring and provide access to structures closely related to the natural products crispine A and harmicine.

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.1745-07-9, you can also check out more blogs about1745-07-9

Synthesis and evaluation of the structural elements in alkylated tetrahydroisoquinolines for binding to CNS receptors

Diseases of the CNS are often complex and involve multiple receptor systems and thus, the treatment options for these diseases must focus on targeting the multiple receptors implicated in the various disorders. Schizophrenia and depression are examples of such diseases and their pharmacotherapy thus depends on agents which target multiple receptors including the dopamine, serotonin and even cholinergic receptors at the same time. In our previous campaign to find multi-receptor ligands, we have identified the benzothiazole 1a as an initial lead molecule. In the current work, we have expanded the structure affinity relationship (SAFIR) of 1a resulting in the identification of a partially restrained butyrophenone 3j as a potent and selective dual 5-HT1Aand 5-HT7receptor ligand. It is expected that compound 3j may serve as a new lead for further development in our search for newer and novel ligands with the potential to treat diseases of CNS origin.

Synthesis and in vitro opioid receptor functional antagonism of analogues of the selective kappa opioid receptor antagonist (3R)-7-hydroxy-N-((1S)-1- {[(3R,4R)-4-(3-hydroxyphenyl)-3,4-dimethyl-1-piperidinyl]methyl}-2-methylpropyl) -1,2,3,4-tetrahydro-3-isoquinolinecarboxamide (JDTic)

In previous structure-activity relationship (SAR) studies, we identified (3R)-7-hydroxy-N-((1S)-1-{[(3R,4R)-4-(3-hydroxyphenyl)-3,4-dimethyl-1- piperidinyl]methyl}-2-methylpropyl)-1,2,3,4-tetrahydro-3- isoquinolinecarboxamide (JDTic, 1) as the first potent and selective kappa opioid receptor antagonist from the trans-3,4-dimethyl-4-(3-hydroxyphenyl) piperidine class of opioid antagonist. In the present study, we report the synthesis and in vitro opioid receptor functional antagonism of a number of analogues of 1 using a [35S]GTPgammaS binding assay. The results from the studies better define the pharmacophore for this class of kappa opioid receptor antagonist and has identified new potent and selective kappa antagonist. (3R)-7-Hydroxy-N-[(1S, 2S)-1-{[(3R,4R)-4-(3-hydroxyphenyl)-3,4- dimethylpiperidin-1-yl]methyl}-2-methylbutyl]-1,2,3,4-tetrahydroisoquinoline-3- carboxamide (3) with a Ke value of 0.03 nM at the kappa receptor and 100- and 793-fold selectivity relative to the mu and delta receptors was the most potent and selective kappa opioid receptor antagonist identified.

Designing analogs of ticlopidine, a wall teichoic acid inhibitor, to avoid formation of its oxidative metabolites

The thienopyridine antiplatelet agent, ticlopidine and its analog, clopidogrel, have been shown to potentiate the action of beta-lactam antibiotics, reversing the methicillin-resistance phenotype of methicillin-resistant Staphylococcus aureus (MRSA), in vitro. Interestingly, these thienopyridines inhibit the action of TarO, the first enzyme in the synthesis of wall teichoic acid, an important cell wall polymer in Gram-positive bacteria. In the human body, both ticlopidine and clopidogrel undergo a rapid P450-dependent oxidation into their respective antiplatelet-active metabolites, resulting in very low plasma concentrations of intact drug. Herein, a series of analogs of ticlopidine and clopidogrel that would avoid oxidative metabolism were designed, prepared and evaluated as inhibitors of TarO. Specifically, we replaced the P450-labile thiophene ring of ticlopidine and clopidogrel to a more stable phenyl group to generate 2-(2-chlorobenzyl)-1,2,3,4-tetrahydro- isoquinoline) (6) and (2-chloro-phenyl)-(3,4-dihydro-1H-isoquinolin-2-yl)-acetic acid methyl ester (22), respectively. The latter molecules displayed inhibitory activity against TarO and formed the basis of a library of analogs. Most synthesized compounds exhibited comparable efficacy to ticlopidine and clopidogrel. So far, it was introduction of a trifluoromethyl group to compound 6, to generate 2-(2-trifluoromethyl-benzyl)-1,2,3,4-tetrahydro-isoquinoline (13) that exhibited enhanced activity against TarO. Compound 13 represents a novel stable inhibitor of TarO with synergistic impact on beta-lactam antibiotics against MRSA and low potential for P-450 metabolism.

A modified Mannich reaction using 1,3-dioxolane

Mannich reaction of ketones using 1,3-dioxolane instead of formaldehyde, paraformaldehyde, or 1,3,5-trioxane afforded the corresponding Mannich bases in high yields. Under the same conditions the aminomethylation of aromatics did not proceed but the intramolecular aminomethylation, like a Pictet-Spengler type reaction, proceeded smoothly.

O-Naphthoquinone-Catalyzed Aerobic Oxidation of Amines to (Ket)imines: A Modular Catalyst Approach

A modular aerobic oxidation of amines to imines has been achieved using an ortho-naphthoquinone (o-NQ) catalyst. The cooperative catalyst system of o-NQ and Cu(OAc)2 enabled the formation of homocoupled imines from benzylamines, while the presence of TFA helped the formation of cross-coupled imines in excellent yields. The current mild aerobic oxidation protocol could also be applied to the oxidation of secondary amines to imines or ketimines with the help of cocatalyst, Ag2CO3, with excellent yields.

Molybdenum trioxide catalyzed oxidative cross-dehydrogenative coupling of benzylic sp3 C-H bonds: Synthesis of alpha-aminophosphonates under aerobic conditions

Molybdenum trioxide (MoO3) catalyzed efficient oxidative cross-dehydrogenative-coupling (CDC) method for C-H functionalization of N-aryl tetrahydroisoquinolines has been explored. This user-friendly method of synthesizing alpha-aminophosphonates employs 1.1 equiv of dialkyl-H- phosphonate under aerobic condition. Formation of new C-P bonds from unfunctionalized starting materials under environmentally benign conditions provides an excellent avenue for the synthesis of biologically active alpha-aminophosphonates.

Discovery of a Novel Class of Negative Allosteric Modulator of the Dopamine D2 Receptor Through Fragmentation of a Bitopic Ligand

Recently, we have demonstrated that N-((trans)-4-(2-(7-cyano-3,4-dihydroisoquinolin-2(1H)-yl)ethyl)cyclohexyl)-1H-indole-2-carboxamide (SB269652) (1) adopts a bitopic pose at one protomer of a dopamine D2 receptor (D2R) dimer to negatively modulate the binding of dopamine at the other protomer. The 1H-indole-2-carboxamide moiety of 1 extends into a secondary pocket between the extracellular ends of TM2 and TM7 within the D2R protomer. To target this putative allosteric site, we generated and characterized fragments that include and extend from the 1H-indole-2-carboxamide moiety of 1. N-Isopropyl-1H-indole-2-carboxamide (3) displayed allosteric pharmacology and sensitivity to mutations of the same residues at the top of TM2 as was observed for 1. Using 3 as an “allosteric lead”, we designed and synthesized an extensive fragment library to generate novel SAR and identify N-butyl-1H-indole-2-carboxamide (11d), which displayed both increased negative cooperativity and affinity for the D2R. These data illustrate that fragmentation of extended compounds can expose fragments with purely allosteric pharmacology.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. 149355-52-2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 149355-52-2, in my other articles.
