A heteroDiels-Alderreaction with inverse electron demand between 4-hydroxycoumarin, aromatic aldehydes and electron-rich alkenes yielded a multitude of 2,4-disubstituted 3,4-dihydropyranocoumarins. This route opened an easy access to coumarin anticoagulants and provided a library of pyranocoumarin derivatives.
