The diastereoselectivity of the intermolecular Diels-Alder reaction of 2-azetidinone-tethered dienes was investigated. Diene precursors were prepared from 4-azetidinone-2-carbaldehydes through an allylation-dehydration process or by the sequence Wittig reaction/enolate trapping. Dienes with a βlacta
