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 ...

Enzymatic intermolecular Diels-Alder reactions in synthesis: From nature to design
Tetrahedron Chem, 2022 The Diels-Alder (D-A) reaction is one of the most critical chemical transformations to construct C–C bonds with predictable regio- and stereo-selectivities. It has been widely used as a retrosynthetic disconnection in synthetic chemistry.

The pentadehydro-Diels–Alder reaction [PDF]
Nature, 2016 In the classic Diels-Alder [4 + 2] cycloaddition reaction, the overall degree of unsaturation (or oxidation state) of the 4π (diene) and 2π (dienophile) pairs of reactants dictates the oxidation state of the newly formed six-membered carbocycle. For example, in the classic Diels-Alder reaction, butadiene and ethylene combine to produce cyclohexene ...

Synthesis of the [11]Cyclacene Framework by Repetitive Diels–Alder Cycloadditions
Molecules, 2021 The Diels–Alder cycloaddition between bisdienes and bisdienophile incorporating the 7-oxa-bicyclo[2.2.1]heptane unit are well known to show high diastereoselectivity that can be exploited for the synthesis of molecular belts. The related bisdiene 5,6,7,8-
