Abstract
Pyridine-2 or 4-carboxaldehyde, furan-2-aldehyde, were condensed on 2-coumaranone and on 5-hydroxy 2-coumaranone to give new ene-lactones analogues of the natural marginalin. Only the addition compounds issued from 2-coumaranone could give stilbene methyl esters and no rearrangement into benzo [b] furan carboxylates could be observed. These observations are discussed in relation with previous results in the series.Keywords
