Synthesis and pharmacological characterization of 2-(4-chloro-3-hydroxyphenyl)ethylamine and N,N-dialkyl derivatives as dopamine receptor ligands was written by Claudi, Francesco;Giorgioni, Gianfabio;Di Stefano, Antonio;Abbracchio, Maria Pia;Paoletti, Anna Maria;Balduini, Walter. And the article was included in Journal of Medicinal Chemistry in 1992.HPLC of Formula: 6834-42-0 This article mentions the following:

2-(4-Chloro-3-hydroxyphenyl)ethylamine (I) and some derivatives were synthesized as dopamine (DA) receptor ligands. Amine I retains the dopaminergic pharmacophore 2-(3-hydroxyphenyl)ethylamine, and the chlorine atom replaces the “para” hydroxyl group of DA. 4,3-Cl(HO)C₆H₃CH₂CH₂NRPr (II, R = Pr, PhCH₂CH₂, 3-MeOC₆H₄CH₂CH₂, 4-MeOC₆H₄CH₂CH₂, 4-MeOC₆H₄CH₂CH₂CH₂) were obtained by introducing on the nitrogen of amine I the n-Pr and 2-phenylethyl or 3-phenylpropyl groups which can be accommodated by the D-2 receptor lipophilic sites 3C and π₃, resp. The affinity and selectivity of these compounds for D-1 and D-2 subtypes was determined in radioligand competition assays for the DA receptors of rat striatum membranes using [³H]SCH 23390 (D-1 selective) and [³H]spiperone (D-2 selective) as radioligands. I shows about 7-fold lower affinity than DA for both sites and is not able to discriminate between the two subtypes of DA receptors. The introduction of two n-Pr groups on the nitrogen atom in II (R = Pr) reduces by one-half and doubles the affinity for D-1 and D-2 binding sites, resp. The substitution of an n-Pr group with different alkylphenyl groups, to give the remaining II, increases the affinity for the D-2 subtype from 19-fold to 36-fold. These compounds have the same affinity at the D-2 site as the DA agonist N-propyl-N-(2-phenylethyl)-2-(3-hydroxyphenyl)ethylamine (III) and are about 20 times more selective than DA for this binding site. In the assay for D-2 receptor mediated inhibition of adenylate cyclase activity, all the tested compounds behaved as D-2 agonists, N-propyl-N-[2(4-hydroxyphenyl)ethylamine was more effective than DA or III. On the other hand, all compounds were less effective than DA in stimulation of adenylate cyclase activity in rat striatal homogenates, a kind of effect which is mediated by the D-1 subtype of DA receptors. These results suggest that the nitrogen substitution enhances the affinity and selectivity for the D-2 receptor. In the adenylate cyclase assay, the compounds behave as potent D-2 agonists. In the experiment, the researchers used many compounds, for example, 2-(3-Methoxyphenyl)acetyl chloride (cas: 6834-42-0HPLC of Formula: 6834-42-0).

2-(3-Methoxyphenyl)acetyl chloride (cas: 6834-42-0) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.HPLC of Formula: 6834-42-0

Diaza-18-crown-6 ethers containing partially-fluorinated benzyl sidearms: Effects of covalently bonded fluorine on the alkali metal complexation was written by Chi, Ki-Whan;Shim, Kwang Taeg;Huh, Hwang;Lee, Uk;Park, Young Ja. And the article was included in Bulletin of the Korean Chemical Society in 2005.Name: 2-(Chloromethyl)-1,3-difluorobenzene This article mentions the following:

The stability constants for the diaza-18-crown-6 ethers (2-6) and alkali metal cations (Na⁺, K⁺, Rb⁺ and Cs⁺) were determined using potentiometry in 95% methanol. For each metal ion the stability constants of the partially-fluorinated ligands 3-6 were larger than that of the non-fluorinated ligand 2, which might reflect an interaction between fluorine atoms and alkali metal cations. The stability constant of the ligand 4 was larger than that of the ligand 5 for each metal cation tested. This finding was also supported by the results of cation-induced chem. shifts in ¹H-, ¹⁹F-NMR and extraction experiment The potentiometry and NMR results as well as the X-ray crystal structures revealed that the position and number of fluorine atoms in the benzyl side arms was crucial for the enhanced interaction between a ligand and an alkali metal. In the experiment, the researchers used many compounds, for example, 2-(Chloromethyl)-1,3-difluorobenzene (cas: 697-73-4Name: 2-(Chloromethyl)-1,3-difluorobenzene).

2-(Chloromethyl)-1,3-difluorobenzene (cas: 697-73-4) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion.

However, the extent of chlorination is difficult to control.Name: 2-(Chloromethyl)-1,3-difluorobenzene

Organometallic compounds of the alkali metals. VII. Orientation in protophilic aromatic metalation by ethylsodium and ethyllithium-potassinm reagents: factors influencing the reactivity of metalating reagents was written by Bryce-Smith, D.. And the article was included in Journal of the Chemical Society in 1963.COA of Formula: C8H10ClN This article mentions the following:

An extension of previous work on the metalation of isopropyl-benzene by alkylsodiums and an EtLi-K complex is described. The isomer ratios for metalation of isopropylbenzene by EtNa are similar at 20° and 85° and very similar to those given by C₅H₁₁Na at 20°: meta-substitution predominates in each case. The total rate factors for nuclear metalation of isopropylbenzene by EtNa and an EtLi-K complex are closely similar, and show that the isopropyl group behaves as a deactivating substituent, in agreement with previous work. Little or no rearrangement appears to occur in the conditions employed, in contrast with the recently reported behavior of related Li-free systems. PhLi-K is less reactive than PhK towards PhMe and PhCl. It is suggested that metalations of the present type may occur in homogeneous spin., notwithstanding the apparent heterogeneity of the reaction systems. In the experiment, the researchers used many compounds, for example, 2-Chloro-N,N-dimethylaniline (cas: 698-01-1COA of Formula: C8H10ClN).

2-Chloro-N,N-dimethylaniline (cas: 698-01-1) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.COA of Formula: C8H10ClN

Enantiodifferentiating photoisomerization of cyclooctene included and sensitized by benzoate modified β-cyclodextrin derivatives: switching of product chirality by solvent was written by Li, Guangxun;Wang, Zhizhong;Lu, Runhua;Tang, Zhuo. And the article was included in Tetrahedron Letters in 2011.COA of Formula: C8H4ClNO This article mentions the following:

Solvent effect upon asym. photosensitization was studied in the enantiodifferentiating photoisomerization of cyclooctene(1Z), sensitized by benzoate modified β-cyclodextrin derivatives bearing nitrogen, oxygen or sulfur substituents. The enantiomeric excess (ee) and E/Z ratio of reaction products were susceptible to the concentration of methanol in the aqueous solution, which could switch to the chirality of product unprecedentedly. Further the conformation of the modified CDs in aqueous methanol solutions with 1Z were highly sensitive to both the substituent(s) on benzoate moiety of the modified CDs and the concentration of methanol. Solvent content represents a new versatile tool to efficiently manipulate the asym. photochem. reactions, in which the chirality of products can be switched by simply changing the methanol content of reaction solvent rather than synthesizing the antipodal sensitizers. In the experiment, the researchers used many compounds, for example, 3-Cyanobenzoyl chloride (cas: 1711-11-1COA of Formula: C8H4ClNO).

3-Cyanobenzoyl chloride (cas: 1711-11-1) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.COA of Formula: C8H4ClNO

The quant. structure-activity relationship (QSAR) for growth-inhibiting activities was also analyzed and established.
