 Title    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).

 Title    Pisatin as a Major Phytoalexin in L a ih y ru s  
 Abstract    The pterocarpan pisatin has been identified as a major phytoalexin in fifteen species of Lathyrus. Thus, the genus is closer in its phytoalexin response to Pisum than to Vicia, which is known to produce furanoacetylenes on fungal in­ vasion.

 Abstract    In response to fungal inoculation the leaves of Trifolium arvense accumulate the known isoflavonoid phytoalexins, medicarpin, maackiain, sativan, vestitol, and isovestitol. A previously undescribed isoflavan derivative (arvensan; 7,2'-dimethoxy-4'-hydroxyisoflavan) is also produced by this species. The identification and synthesis of arvensan is described.

 Title    of the Genus Caragana  
 Abstract    The fungus-inoculated leaflets of 39 Caragana species have been found to variously produce five isoflavonoid phytoalexins including the known pterocarpan derivatives, medicarpin, maackiain, variabilin and pisatin. Small quan­ tities of a previously undescribed C-methylated pterocarpan were obtained from leaflets of C. acanthophylla.

 Title    Isoflavonoid Phytoalexins of Yam Bean (Pachyrrhizus erosus)  
 Abstract    The furanopterocarpan, neodunol, has been isolated as a major phytoalexin from the fungus-inoculated stems o f Pachyrrhizus erosus. N eodunol is accompanied by small quantities o f dem -ethylmedicarpin and a third compound provisionally identified as the prenylated pterocarpan, ho-moedudiol; traces o f a neodunol isomer were also isolated from P. erosus although its precise struc­ ture could not be determined. The apparently close chemical relationship between Pachyrrhizus and Neorautanenia is discussed in the light o f a recent study which allocates these genera to differ­ ent sections o f the legum e tribe Phaseoleae.

 Title    The Structure of Desmocarpin, a Pterocarpan Phytoalexin from Desmodium gangeticum  
 Abstract    Ethyl acetate extracts o f diffusates from the fungus-inoculated leaflets o f Desm odium gangeti­ cum have been found to contain six isoflavonoid phytoalexins including the isoflavones genistein and 2'-hydroxygenistein, and the isoflavanones dalbergioidin, dip hysolone and kievitone. These known phytoalexins occur together with a new antifungal isoflavonoid (desm ocarpin) for which the structure (—)-(6a/?; 1 la/?)-l,9-dihydroxy-3-m ethoxypterocarpan is proposed.

 Abstract    Further investigation o f the isoflavonoids in white lupin roots has revealed a new coum a­ ronochromone with a 2-hydroxy-3-methyl-3-butenyl side chain (lupinalbin G), three new pyrano-isoflavones (lupinisoflavones K and L, and allolicoisoflavone B) and two new di-hydrofurano-isoflavones each with a 2,3-dihydroxy-3-m ethylbutyl substituent (lupinisofla­ vones M and N). The biogenetic pathways for these and other lupin isoflavones are briefly discussed.

 Title    Chromene Chalcones from Tephrosia carrollii and the Revised Structure of Oaxacacin^  
 Abstract    The aerial parts of Tephrosia carrollii afforded two chromene chalcones. Their structures and stereochemistry were established by spectroscopic methods. The structure of oaxacacin was revised and confirmed by X-ray diffraction. In this paper, we describe the isolation of the chalcone known as "oaxacacin" and the new chalcone named epoxyobovatachalcone. The compound der. oaxacacin was found to be identical with obovatachalcone based on spectroscopic evidence and X-ray diffraction.

 Title    Phytoalexins from Dolichos biflorus  
 Abstract    , 2'-hydroxygenistein, dalbergioidin, kievitone and phaseollidin have been found to accumulate in leaves and stems of Dolichos biflorus (horsegram) following inoculation with the non-pathogens Pseudomonas pisi and Phytophthora megasperma f. sp. glycinea, respectively. They are accompanied by isoferreirin (5,7,4'-trihydroxy-2'-methoxyisoflavanone), a compound not previously reported as a natural product. Coumestrol and psoralidin occur constitutively in Dolichos leaves and stems.
