Diels-Alder Cycloadditions of Electron-Rich, Electron-Deficient, and Push-Pull Dienes with Cyclic Dienophiles: High-Pressure-Induced Reactions and Theoretical Calculations

Article abstract of DOI:10.1021/jo00013a012

High-pressure-promoted (4 + 2) cycloadditions of cyclic dienophiles (mainly β-angelica lactone and cyclopentenone) with electron-rich and push-pull hetero-substituted dienes have been investigated.Only one regio- and stereoisomer was obtained in all cases
