Dibenzonaphthyridinones: Heterocycle-to-Heterocycle Synthetic Strategies and Photophysical Studies [PDF]

, 2015
A heterocycle-to-heterocycle strategy is presented for the preparation of highly fluorescent and solvatochromic dibenzo­naph­thyridinones (DBNs) via methodology that leads to the formation of a tertiary, spiro-fused carbon center.

Pseudocyclic Bis-N-Heterocycle-Stabilized Iodanes – Synthesis, Characterization and Applications [PDF]

, 2021
In this manuscript we describe novel bicationic iodonium salts which are stabilized by covalently connected N-heterocycles (Bis-N-Heterocycle-stabilized Iodanes BNHIs). We provide structural data, their synthesis as well as their application in benchmark

Iron-Catalyzed Stereospecific Heterocycle N-Glycosylation with Glycal Epoxides. [PDF]

Org Lett
Stereospecific N-glycosylation of heterocycles with glycal epoxides could readily provide valuable building blocks for drug discovery, but heterocycle N-glycosylation with a pyranose-based glycal epoxide is still difficult using existing methods.

Heterocycle–Heterocycle Strategies: (2-Nitrophenyl)isoxazole Precursors to 4‑Aminoquinolines, 1H‑Indoles, and Quinolin-4(1H)‑ones

, 2016
Reductive heterocycle–heterocycle (heterocycle → heterocycle; H–H) transformations that give 4-aminoquinolines, 3-acylindoles, and quinolin-4(1H)-ones from 2-nitrophenyl substituted isoxazoles are reported. When this methodology is applied to 3,5-, 4,5-,

Theretofore Highest Efficiency in Vacuum-Deposited Organic Solar Cells Originating From Triarylamine-Based Small-Molecule Donors Containing Fused Heterocycle Units. [PDF]

Adv Sci (Weinh)
Fused‐ring engineering unlocks record efficiency in vacuum‐deposited organic solar cells. By replacing linear π‐bridges with fused‐ring analogues in triarylamine‐based donors, we achieve enhanced molecular planarity, red‐shift optical absorption, minimize energy loss and optimized phase separation.
