title: Intramolecular Diels-Alder reactions of cycloalkenones: translation of high endo selectivity to trans junctions.
abstract: Intramolecular Diels-Alder reactions of cyclobutenone and larger cycloalkenones are described. High levels of endo addition attained from Lewis acid catalysis translate to trans hydrindene junctions upon fragmentation of the tricyclic adducts.
