Synthesis, Functionalization, and Reactivity of Vinyl Sulfondiimidamides

open access: yesAngewandte Chemie, EarlyView.
Combining unsymmetrical sulfurdiimide reagents (R‐NSN‐R1) and Grignard reagents, followed by oxidative amination, delivers a series of vinyl sulfondiimidamides. Reactivity with cysteine and lysine derivatives is shown, and the cysteine reactivity is mapped in detail. Variation of the two imidic N‐substituents can be used to tune reactivity of these new

The Pictet-Spengler Reaction Updates Its Habits

open access: yesMolecules, 2020
The Pictet-Spengler reaction (P-S) is one of the most direct, efficient, and variable synthetic method for the construction of privileged pharmacophores such as tetrahydro-isoquinolines (THIQs), tetrahydro-β-carbolines (THBCs), and polyheterocyclic ...

Visible-light promoted atom transfer radical addition-elimination (ATRE) reaction for the synthesis of fluoroalkylated alkenes using DMA as electron-donor [PDF]

open access: yes, 2020
Here, we describe a mild, catalyst-free and operationally-simple strategy for the direct fluoroalkylation of olefins driven by the photochemical activity of an electron donor-acceptor (EDA) complex between DMA and fluoroalkyl iodides.

2-[(1R,3S)-6,7-Dimethoxy-1-phenyl-1,2,3,4-tetrahydroisoquinolin-3-yl]-4-phenyl-1,3-thiazole

open access: yesActa Crystallographica Section E, 2011
In the title compound, C26H24N2O2S, the dihedral angle between the thiazole ring and the adjacent phenyl ring is 3.02 (15)°. The N-containing six-membered ring of the tetrahydroisoquinoline unit adopts a half-chair conformation.

Microwave-assisted synthesis of 1,2,3,4-tetrahydroisoquinoline sulfonamide derivatives and their biological evaluation [PDF]

open access: yesJournal of the Serbian Chemical Society, 2021
Herein we report an alternative eco-friendly method for the synthesis of 1,2,3,4-tetrahydroisoquinoline sulfonamide derivatives. All obtained compounds were screened for their in vitro inhibition of albumin denaturation, antioxidant, antitryptic and ...

Crystal structure and Hirshfeld surface analysis of 2-{[7-acetyl-4-cyano-6-hydroxy-8-(4-methoxyphenyl)-1,6-dimethyl-5,6,7,8-tetrahydroisoquinolin-3-yl]sulfanyl}acetic acid ethyl ester

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2022
In the title molecule, C25H28N2O5S, (alternative name ethyl 2-{[7-acetyl-4-cyano-6-hydroxy-8-(4-methoxyphenyl)-1,6-dimethyl-5,6,7,8-tetrahydroisoquinolin-3-yl]sulfanyl}acetate) the 4-methoxyphenyl group is disposed on one side of the bicyclic core and ...

Structure–activity study of N-((trans)-4-(2-(7-cyano-3,4-dihydroisoquinolin-2(1H)-yl)ethyl)cyclohexyl)-1H-indole-2-carboxamide (SB269652), a bitopic ligand that acts as a negative allosteric modulator of the dopamine D2 receptor [PDF]

open access: yes, 2015
We recently demonstrated that SB269652 (1) engages one protomer of a dopamine D2 receptor (D2R) dimer in a bitopic mode to allosterically inhibit the binding of dopamine at the other protomer.

4-[(2,4-Dimethyl-1,3-oxazol-5-yl)methyl]-4-hydroxy-2-methylisoquinoline-1,3(2H,4H)-dione

open access: yesActa Crystallographica Section E, 2010
In the title isoquinolinedione derivative, C16H16N2O4, the piperidine ring in the tetrahydroisoquinoline unit adopts a half-boat conformation. The essentially planar oxazole ring [maximum deviation = 0.004 (2) Å] is inclined ...
