Strategies in the synthesis of dibenzo[b,f]heteropines [PDF]

open access: yesBeilstein Journal of Organic Chemistry, 2023
The dibenzo[b,f]azepine skeleton is important in the pharmaceutical industry, not only in terms of existing commercial antidepressants, anxiolytics and anticonvulsants, but also in reengineering for other applications. More recently, the potential of the

A DFT Study on the Mechanism of Selective Formation of Substituted Azepines From 1-Azabutadienes and Cyclopropanes. [PDF]

open access: yesChemistry
The origin of the unusual regioselectivity in the Mg‐catalyzed cyclization of azadiene‐type imines with cyclopropanes is elucidated by DFT calculations. Although five‐membered rings are typically favored, energy decomposition analysis reveals that severe steric congestion induces a highly distorted transition state, rendering the five‐membered pathway ...

Design and synthesis of novel rigid dibenzo[b,f]azepines through ring closure technique as promising anticancer candidates against leukaemia and acting as selective topoisomerase II inhibitors and DNA intercalators [PDF]

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2023
In this research, two novel series of dibenzo[b,f]azepines (14 candidates) were designed and synthesised based on the rigidification principle and following the reported doxorubicin’s pharmacophoric features. The anti-proliferative activity was evaluated

Photoinduced Solution‐Stable Radicals via Intramolecular Charge Separation From anti‐Kasha Emissive BN‐Azepines

open access: yesElectron
Persistent and stable radicals remain challenging to generate via photoinduction, despite their vast potential in magnetics and energy storage. Trisubstituted amines offer a promising platform for photoinduced radicals, but rapid charge recombination ...

Synthesis and molecular docking simulations of novel azepines based on quinazolinone moiety as prospective antimicrobial and antitumor hedgehog signaling inhibitors [PDF]

open access: yesScientific Reports
A series of novel azepine derivatives based on quinazolinone moiety was synthesized through the reaction of quinazolinone chalcones (2a–d) either with 2-amino aniline in acidic medium to give diazepines (3a–d) or with 2-aminophenol to offer oxazepine (4a–

Synthesis and antimicrobial activity of azepine and thiepine derivatives [PDF]

open access: yesJournal of the Serbian Chemical Society, 2015
A series of new 5H-pyridobenzazepine and pyridobenzothiepine derivatives was synthesized by Pd-catalyzed formation of C-N and C-S bonds. All synthesized compounds were tested for their in vitro antimicrobial activity.
