Condensation of 7-benzyloxy-6,2',3',4'-tetramethoxyisoflavylium perchlorate (1; R = PhCH2) with 1-(3,4-dimethoxyphenyl)-3-(2,4-dimethoxyphenyl)prop-1-ene (2) and with its isomeric propene gave derivatives provisionally formulated as the 6-benzyl-5-phenylbenzoxanthenes (type 6; R1=OMe, R2= PhCH2) analogous to the xanthenes derivable from per-O-methylsantarubin and per-O-methylsantalin, respectively.
TRANSFORMATION DU CATION ISOFLAVYLIUM EN PHENYL-3 COUMARINES, ISOFLAVENES-3 ET ISOFLAVANNES
Deschamps-Vallet, Colette,Ilotse, Jean-Baptiste,Meyer-Dayan, Michele
, p. 3993 - 3996 (2007/10/02)
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.
