| Induced Isoflavonoids from Fungus-Infected Stems of Pigeon Pea ( Cajanus cajan)  | | | | Abstract
| Four antifungal isoflavones [7-hydroxy-4'-methoxy-(l) ; 5,7,4'-trihydroxy-(2) ; 5,7,2',4'-tetra-hydroxy-(3) ; 5,2',4'-trihydroxy-7-methoxy-(4) ] and one isoflavanone [ (5,2'-dihydroxy-7,4'-dimeth-oxy-(7)] have been isolated from the fungus-infected stems of C ajanus cajan . A sixth compound has been provisionally identified as 5,2'-dihydroxy-7,4'-dimethoxyisoflavone (5). The structure of 5,2'-dihydroxy-7,4'-dimethoxyisoflavanone (cajanol) was confirmed by synthesis from ferreirin (S^^'-trihydroxy^'-methoxyisoflavanone). | | | |

| | | | | Abstract
| Peroxide oxidation of cajanol ethyl ether afforded the B ring derived product, 2-methoxy-4-ethoxybenzoic acid. For mation of this compound means that the structure of cajanol, a major phytoalexin from Cajanus cajan, must be revised to 5,4'-dihydroxy-7,2'-dimethoxyisoflavanone. | | | |
