Unusual Structure-Energy Correlations in Intramolecular Diels–Alder Reaction Transition States [PDF]
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 ...

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