Journal of the American Chemical Society, 2019 Diels–Alder reactions are among the most powerful synthetic transformations to construct complex natural products. Despite that increasing of enzymatic intramolecular Diels–Alder reactions have been discovered, natural intermolecular Diels–Alderases are ...

Journal of the American Chemical Society, 2019 The pericyclases are a growing superfamily of enzymes that catalyze pericyclic reactions. We report a pericyclase IccD catalyzing an inverse-electron demand Diels–Alder (IEDDA) reaction with a rate acceleration of 3 × 105 fold in the biosynthesis of ...

Diels–Alder Cycloaddition Reactions in Sustainable Media
Molecules, 2022 Diels–Alder cycloaddition reaction is one of the most powerful strategies for the construction of six-membered carbocyclic and heterocyclic systems, in most cases with high regio- and stereoselectivity.

Inter- and intramolecular Diels-Alder/retro-Diels-Alder reactions of 4-silylated oxazoles [PDF]
, 2002 4-Silylated oxazoles have been shown to undergo inter- and intramolecular Diels-Alder/retro-Diels-Alder reactions with electron-poor alkynes to generate polysubstituted furans.

Oxidative [4+2] annulation of styrenes with alkynes under external-oxidant-free conditions
Nature Communications, 2018 A sequence of a Diels–Alder reaction and oxidation is a powerful route to valuable aromatic compounds. Here, the authors report a more atom-economical oxidant-free strategy involving a Diels–Alder with H2 evolution under noble-metal-free photoredox ...

Computational design of an enzyme catalyst for a stereoselective bimolecular Diels-Alder reaction
Science, 2010 Biocatalytic Boost Enzymes tend to direct reactions toward specific products much more selectively than synthetic catalysts. Unfortunately, this selectivity has evolved for cellular purposes and may not promote the sorts of reactions chemists are seeking
