The direct synthesis of isoflavans VIA α-alkylation of phenylacetates

Deprotonation of oxygenated phenylacetates and quenching of the enolates with oxygenated benzylic electrophiles, afforded 2,3-diarylpropanoates which served as precursors to the isoflavans following consecutive reduction and cyclization steps.

TRANSFORMATION DU CATION ISOFLAVYLIUM EN PHENYL-3 COUMARINES, ISOFLAVENES-3 ET ISOFLAVANNES

Isoflavylium salts 1 are key starting materials for synthesis of 3-phenyl coumarins 2,isoflav-3-enes 4 and isoflavans 5, by chemical conversions narrowsly apparented to biogenetic pathways actually recognized for natural compounds of these series.
