Unusual Structure-Energy Correlations in Intramolecular Diels–Alder Reaction Transition States [PDF]
Molecules, 2014 Detailed analysis of calculated data from an experimental/computational study of intramolecular furan Diels–Alder reactions has led to the unusual discovery that the mean contraction of the newly forming C-C σ-bonds from the transition state to the ...

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

Screening of chiral Diels-Alder catalysts by mass spectrometric monitoring of the retro reaction [PDF]
, 2007 A rapid screening procedure for the identification of chiral Diels-Alder catalysts by ESI MS was developed. Screening of the retro reaction made it possible to indirectly determine the catalyst’s enantioselectivity for the forward, product-forming ...
