2‐Aminoindoles and 2‐Iminoindolines as Viable Precursors of Indole‐Fused Nitrogenated Polyheterocycles

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 6, March 18, 2025.
Abstract The synthesis of architecturally complex polyheterocyclic structures embedding the indole ring represents a growing field of interest. Carbolines and their partially dehydro derivatives, pyrazinoindoles, indoloindoles, azepinoindoles and other medium‐sized derivatives are only some examples of indole‐containing polycyclic compounds featured by

Shifting Lithium Amide Reactivity to the Radical Domain: Regioselective Radical C−H Functionalization of 3‐Iodooxetane for the Synthesis of 1,5‐Dioxaspiro[2.3]hexanes

open access: yesAngewandte Chemie, Volume 137, Issue 15, April 7, 2025.
Strained spirocyclic 1,5‐dioxaspiro[2.3]hexanes were synthesized via a lithium‐amide induced single‐electron transfer to a series of non‐enolizable ketones generating a frustrated radical pair‐like N‐centered radical and ketyl radical anion. This pair works synergistically to selectively abstract the β‐hydrogen from 3‐iodooxetane, initiating a radical ...

Advancing the Identification of Bioactive Molecules and the Construction of a Synergistic Drug Delivery System in Combating Lung Injury

open access: yesAdvanced Science, Volume 12, Issue 18, May 15, 2025.
Traditional Chinese Medicine (TCM), while holistic and historically esteemed, faces challenges in “miracle cures” due to slow onset, long cycles, and difficulty controlling quality. This study obtains the active ingredients, glabridin (GLA) and puerarin (PUE), from Ge‐Gen Decoction (GGD), developing a safe and effective drug delivery system, GLA‐PUE ...
