Synthesis of Fused Heterocycles: 1,2,3,4-Tetrahydroisoquinolines and Ring Homologues via Sulphonamidomethylation

The title heterocycles (3) have been obtained by a two-step synthesis; namely an initial intramolecular sulphonamidomethylation of N-aralkylsulphonamides (1) in acid media followed by desulphonylation of compounds (2) under moderate conditions, either by reduction or acid hydrolysis.Generally both steps gave good or high yields of compounds (3) variously substituted in the aromatic ring and with a six-, seven-, or eight-membered heterocyclic ring.

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.name: 7-Chloro-1,2,3,4-tetrahydroisoquinoline, you can also check out more blogs about82771-60-6

Iodine release and recovery, influence of polyiodide anions on electrical conductivity and nonlinear optical activity in an interdigitated and interpenetrated bipillared-bilayer metal-organic framework

{[Cu6(pybz)8(OH)2]¡¤I 5-¡¤I7-}n (1), obtained hydrothermally by using iodine molecules as a versatile precursor template, consists of a cationic framework with two types of zigzag channels, which segregate I5- and I7- anions. The framework exhibits the first observed bipillared-bilayer structure featuring both interdigitation and interpenetration. 1 displays high framework stability in both acidic (HCl) and alkaline (NaOH) solutions. 1 slowly releases iodine in dry methanol to give [Cu6(pybz)8(OH)2](I -)2¡¤3.5CH3OH (1′) and partially recovers iodine from cyclohexane to form [Cu6(pybz)8(OH) 2](I-)2¡¤xI2 (1?). Differences of up to 100 times in electrical conductivity and of 4 times in nonlinear optical activity (NLO) have been measured between 1 and 1′. This compound is one of few displaying multifunctionality, electrical conductivity, NLO, and crystal-crystal stability upon release and recovery of iodine. It is also unique in the iodine release from polyiodide anions in a metal-organic framework.

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 57196-62-0, help many people in the next few years.SDS of cas: 57196-62-0

Visible light photoredox catalysis: Generation and addition of N -aryltetrahydroisoquinoline-derived alpha-amino radicals to michael acceptors

The photoredox-catalyzed coupling of N-aryltetrahydroisoquinoline and Michael acceptors was achieved using Ru(bpy)3Cl2 or [Ir(ppy)2(dtb-bpy)]PF6 in combination with irradiation at 455 nm generated by a blue LED, demonstrating the trapping of visible light generated alpha-amino radicals. While intermolecular reactions lead to products formed by a conjugate addition, in intramolecular variants further dehydrogenation occurs, leading directly to 5,6-dihydroindolo[2,1-a] tetrahydroisoquinolines, which are relevant as potential immunosuppressive agents.

Substituted 2-phenylimidazopyridines: A new class of drug leads for human African trypanosomiasis

A phenotypic screen of a compound library for antiparasitic activity on Trypanosoma brucei, the causative agent of human African trypanosomiasis, led to the identification of substituted 2-(3-aminophenyl)oxazolopyridines as a starting point for hit-to-lead medicinal chemistry. A total of 110 analogues were prepared, which led to the identification of 64, a substituted 2-(3-aminophenyl)imidazopyridine. This compound showed antiparasitic activity in vitro with an EC50 of 2 nM and displayed reasonable druglike properties when tested in a number of in vitro assays. The compound was orally bioavailable and displayed good plasma and brain exposure in mice. Compound 64 cured mice infected with Trypanosoma brucei when dosed orally down to 2.5 mg/kg. Given its potent antiparasitic properties and its ease of synthesis, compound 64 represents a new lead for the development of drugs to treat human African trypanosomiasis.

Basicity pK(HB) scale of hydrogen bounding of aliphatic tertiary amines

The hydrogen bond acceptor strength of 40 tertiary amines has been measured by Fourier transform – infrared (FTIR) spectrometry from their 1:1 complexation constant towards 4-fluorophenol in CCl4 at 25C (the pKHB scale). Also measured was the frequency shift, Deltanu(OH), of the nu(OH) band of methanol hydrogen-bonded to these amines. The comparison of the thermodynamic hydrogen bond basicity scale, pKHB, with the spectroscopic one, Deltanu(OH), and with the Bronsted pKa scale, points to the great sensitivity of pKHB to steric effects. The pKHB scale of tertiary amines extends from 2.71 for quinuclidine to -0.34 for N,N-diisopropyl-3-pentylamine. The main factors governing this important variation (17 kJ¡¤mol-1 on the Gibbs energy scale) are the electron-withdrawing inductive effect and various kinds of steric effects (e.g., opening of the CNC angles and hindrance to OH fixation on the nitrogen lone pair). Infrared (IR) spectra show the attachment of 4-fluorophenol to the nitrile nitrogen of Me2NCH2C?N and Me2NCH2CH2C?N, to the oxygen of N-methylmorpholine, and to the pi electrons of (HC?CCH2)3N and (PhCH2)3N, in addition to the attachment to the amino nitrogen. In (PhCH2)3N, the electron-withdrawing effect of the three benzyl substituents and, mainly, the very important congestion of the nitrogen lone pair reduce the nitrogen hydrogen-bond basicity almost to nothing, so that tribenzylamine, a nitrogen Bronsted base, turns to a pi base in hydrogen bonding. From this example, the large differences between the pKHB and pKa scales of organic bases are emphasized.

Rigid: Versus flexible anilines or anilides confirm the bicyclic ring as the hydrophobic portion for optimal sigma2 receptor binding and provide novel tools for the development of future sigma2 receptor PET radiotracers

Despite their uncertain identification, sigma2 receptors are promising targets for the development of diagnostics and therapeutics for tumor diseases. Among the sigma2 ligands developed, the class of the flexible benzamides furnished an optimal pharmacophore for sigma2 receptor high affinity ligands. A recent investigation suggested that flexible benzamides bind sigma2 receptors in a bicyclic-like conformation due to an intramolecular H-bond, with 3,4-dihydroisoquinolinone derivatives reaching excellent sigma2 affinity and selectivity. Herein, the bicyclic-preferred conformation for sigma2 binding was confirmed through the development of 3,4-dihydroquinolin-(1H)2-one isomeric derivatives, 1,2,3,4-tetrahydroquinolines and the corresponding flexible anilides and anilines, all linked to the 6,7-dimethoxytetrahydroisoquinoline as a basic moiety. 3,4-Dihydroisoquinolin-(1H)2-one (10a) and 1,2,3,4-tetrahydroisoquinoline (11b) emerged for high sigma2 affinity combined to an excellent sigma2versus sigma1 selectivity. In particular, compound 11b with its low nanomolar sigma2 affinity and impressive 2807-fold sigma2versus sigma1 selectivity largely exceeded the biological profile of the best 3,4-dihydroisoquinolin-(2H)1-one reference compounds (1). Because of the absence of a cytotoxic effect, the modest interaction with the P-gp, an appropriate lipophilicity and the presence of easily radiolabeling functions, 11b deserves further investigation for the imaging of sigma2 receptors via PET in tumors.
