	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.

	Title
	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.

	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.

	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.
