Author is Tan, Bryan Yong-Hao; Teo, Yong-Chua.

A convenient protocol for the C-N cross-coupling of aliphatic amides and iodobenzene is demonstrated using a simple and inexpensive Co(C2O4)·2H2O/N,N’-dimethylethylenediamine (DMEDA) catalytic system in water. Good yields of N-arylated products I [R1 = Pr, i-Pr, Bu, etc; R2 = Ph, 2-F-C6H4, 4-Me-C6H4, etc.] were isolated (up to 85%) and the protocol has been successfully applied to the synthesis of the anticancer drug, flutamide.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthesis and pharmacological evaluation of benzamide derivatives as potent and selective sigma-1 protein ligands, published in 2017-09-29, which mentions a compound: 7661-33-8, mainly applied to aminoalkyl benzamide preparation sigma protein cytotoxicity human docking SAR; benzyl methyl propanamine preparation sigma protein safety human SAR; Benzamide; CNS; Sigma protein, Category: alcohols-buliding-blocks.

A series of novel N-(aminoalkyl)benzamide derivatives such as I [m = 2, 3; R1 = Me; R2 = Bn, (CH2)2C6H4; R1R2 = (CH2)4, (CH2)2O(CH2)2, (CH2)2NMe(CH2)2, etc.; R3 = H, 4-n-Bu, 4-Cl, etc.] and N-benzyl-N-methyl-propan-1-amine derivatives II [X = CH2NH, SO2NH, NHC(O)] was designed, synthesized and pharmacol. evaluated. In vitro competition binding assays against sigma proteins (sigma-1 S1R and sigma-2 S2R) revealed that most of them conferred S2R/S1R selectivity toward without cytotoxic effects on SY5Y cells, especially with compounds I [m = 2, 3; R1 = Me; R2 = Bn]. Some selected compounds were also evaluated for their agonist and antagonist activities on a panel of 40 receptors and results showed the importance of the nature and the position with halogeno atom on the benzamide scaffold, the length chain and also the contribution of the hydrophobic part on the amine group. Among them, compounds I [m = 2, 3; R1 = Me; R2 = Bn; R3 = 4-Cl, 4-CN, 4-NO2] showed excellent affinity for S1R (Ki = 1.2-3.6 nM), selectivity for S2R (Ki up to 1400 nM) and high selectivity index (IC50(SY5Y)/Ki(S1R) ratio from 28/000 to 83/000). Furthermore, these compounds I and II presented an excellent safety profile over 40 other receptors.

HPLC of Formula: 7661-33-8. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 1-(4-Chlorophenyl)pyrrolidin-2-one, is researched, Molecular C10H10ClNO, CAS is 7661-33-8, about Lactams. VIII. Conformation of N-aryl lactams. Author is Manhas, Maghar S.; Jeng, Stella J.; Bose, Ajay K..

N-Aryl β-lactams were characterized by strong uv maximum at about 250 mμ. Some N-aryl γ-lactams also show similar absorption maximum but heavily substituted γ-lactams or N-phenyl δ-lactam display only low absorption in this region. A study of uv and N.M.R. spectra indicates that in N-aryl β-lactams, the heterocyclic ring and the three valences of N are planar and the N-aryl ring lies in the plane of the β-lactam. This planarity as well as the strong uv absorption are the result of an extended conjugation between the aryl ring and the amide function. Ortho substitution on the aryl ring causes a slight departure from this planarity and reduces the intensity of the uv absorption. In case of N-aryl γ-lactams, ortho substitution on the aryl ring causes enough departure from planarity to eliminate altogether the absorption maximum near 250 mμ. 22 references.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Photochemistry of dicyanopyridines, published in 1995-09-13, which mentions a compound: 1195-58-0, mainly applied to photochem dicyanopyridine UV laser flash photolysis, Recommanded Product: Pyridine-3,5-dicarbonitrile.

The photochem. of a variety of dicyanopyridines (2,3-, 2,4-, 2,5-, 2,6-, 3,4- and 3,5-dicyanopyridine) in solution at room temperature was investigated. Pulsed UV (308 nm) laser irradiation in deoxygenated acetonitrile yields the triplet state with lifetimes between 4 and 10 μs and absorption bands in the 400 and 320 nm regions. In the presence of added HCl an air-insensitive transient (τ≈10-12 μs, λmax≈360-380 nm) was observed, suggesting the formation of a protonated excited state. Irradiation in the presence of amines resulted in the production of the pyridyl radical anion (τ≈40-80 μs, air sensitive, λmax≈360-380 nm) formed by electron transfer from the amine to the pyridine triplet excited state. Stern-Volmer anal. gave electron transfer rate constants in the range (1-8)×10-8 M-1s-1. In methanol solvent, irradiation yielded an air-insensitive transient assigned as the neutral pyridyl radical (τ≈30-200 μs, λmax≈370-385 nm). The formation of these transients is discussed in the context of previous photochem. ESR and product studies.

The nonselective glucocorticoid receptor (GR) antagonist mifepristone has been approved in the U.S. for the treatment of selected patients with Cushing’s syndrome. While this drug is highly effective, lack of selectivity for GR leads to unwanted side effects in some patients. Optimization of the previously described fused azadecalin series of selective GR antagonists led to the identification of CORT125134, which is currently being evaluated in a phase 2 clin. study in patients with Cushing’s syndrome.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Canadian Journal of Chemistry called Photochemistry of matrix-isolated 5-cyano-2H-pyran-2-one (δ-cyano-α-pyrone) and cyanocyclobuta-1,3-diene, Author is Menke, Jessica L.; McMahon, Robert J., which mentions a compound: 1195-58-0, SMILESS is N#CC1=CC(C#N)=CN=C1, Molecular C7H3N3, COA of Formula: C7H3N3.

Matrix-isolation photochem. (λ > 299 nm; Ar, 10 K) of 5-cyano-2H-pyran-2-one (5, δ-cyano-α-pyrone) shows complete conversion to a mixture of several ring-opened ketene isomers (6) and a ring-closed Dewar lactone (7), as detected by IR spectroscopy. Subsequent irradiation (λ > 200 nm) causes decarboxylation of the Dewar lactone (7) to produce cyanocyclobuta-1,3-diene (8). Continued irradiation (λ > 200 nm) results in the photodecomposition of cyanocyclobuta-1,3-diene (8) to cyanoacetylene and acetylene. 4-Cyanopyridine (10) was explored as an alternative photochem. precursor to cyanocyclobuta-1,3-diene (8). It was found, however, that 10 does not exhibit observable photochem. under our irradiation conditions.
