Carapa guyanensis

Chisocheton paniculatus 64) yielded 6a-acetoxyepoxyazadiradione (11), previously isolated from Carapa guyanensis 129), and four new azadirone derivatives, only one of which had a furan ring. This was identified as 60c-acetoxy-l P-hydroxyazadiradione (12), from the similarity of the spectrum to that of 17P-hydroxyazadiradione described by Kraus 111).
