Thermally Induced Intramolecular Diels–Alder Reaction of Furan-Tethered Methylenecyclopropanes [PDF]

open access: yesMolecules
The substantial ring strain and activated double bonds render methylenecyclopropanes (MCPs) potential substrates for Diels–Alder (DA) reactions. In this work, we present a thermally induced intramolecular Diels–Alder (IMDA) reaction utilizing furan ...

Intramolecular Imino Diels-Alder Reaction: Progress toward the Synthesis of Uncialamycin [PDF]

open access: yes, 2009
We herein described an intramolecular imino Diels-Alder reaction promoted with BF3.OEt2/DDQ affording substituted quinolines. Using this procedure, we prepared the chiral quitioline moiety of the uncialamycin, a new enediyne natural ...

Exo-selective intermolecular Diels–Alder reaction by PyrI4 and AbnU on non-natural substrates

open access: yesCommunications Chemistry, 2021
Diels-Alderases remain rare in nature, particularly those catalysing intermolecular reactions. Here two natural Diels-Alderases are shown to catalyse exo-selective intermolecular Diels-Alder reactions on non-natural substrates.

Diaza-1,3-butadienes as Useful Intermediate in Heterocycles Synthesis

open access: yesMolecules, 2022
Many heterocyclic compounds can be synthetized using diaza-1,3-butadienes (DADs) as key structural precursors. Isolated and in situ diaza-1,3-butadienes, produced from their respective precursors (typically imines and hydrazones) under a variety of ...

The application of the Diels-Alder reaction to polymer syntheses based on furan/maleimide reversible couplings

open access: yesPolímeros, 2005
The furan heterocycle is a dienic reagent particularly suitable for the Diels-Alder reaction and maleimides represent a typical family of complementary reagents because of their strong dienophilic character.
