INDONESIAN MEDICINAL-PLANTS .13. CHEMICAL STRUCTURES OF CAESALDEKARIN-C, CAESALDEKARIN-D, AND CAESALDEKARIN-E, 3 ADDITIONAL CASSANE-TYPE FURANODITERPENES FROM THE ROOTS OF CAESALPINIA MAJOR (FABACEAE) - SEVERAL INTERESTING REACTION-PRODUCTS OF CAESALDEKARIN-A PROVIDED BY N-BROMOSUCCINIMIDE TREATMENT

Following the previous studies on caesaldekarins a (1) and b (2), the chemical structures of three additional cassane-type furanoditerpenes named caesaldekarins c (3), d (4), and e (5), isolated from the roots of Caesalpinia major (Fabaceae) collected in Flores Island, Indonesia, have been elucidated on the bases of physicochemical evidence and che mical derivations. several interesting NBS (N-bromosuccinimide) reacti on products of 1 have the been elucidated.
