In the presence of a cinchona alkaloid as a catalyst, the Diels-Alder reaction of 3-hydroxy-2-pyrone with chiral N-acryloyl oxazolidinone afforded a bicyclolactone adduct with high diastereoselectivities (up to 95%de) in almost quantitative yield.
Asymmetric total synthesis of (+)-epiepoformin was achieved in short steps using the base-catalyzed asymmetric Diels-Alder (DA) reaction of 3-hydroxy-2-pyrone with chiral acrylate. Since the synthesis produced Ogasawara's intermediate, it is also presented as a formal synthesis of (-)-theobroxide.
