Predictions from DFT (B3LYP/6-31 G(d))-computed stereoisomer product distributions for intramolecularDiels-Alder (IMDA) reactions have been successfully replicated in the laboratory. Benzo-tethered hexadienyl acrylates generally undergo moderately trans-selective IMDA reactions which, as suggested by DFT calculation, arise from two opposing transition structure (TS) features: stabilising secondary
