Monoterpene Alkaloids of Scaevola racemigera D ÄNIKER Nine alkaloids have been isolated from the aerial parts of Scaevola racemigera . Two of them are the known compounds cantleyine ( 1 ) and tetrahydrocantleyine ( 2 ). The seven others are novel alkaloids, strychnovoline ( 3 ), 6‐ O ‐nicotinoylstrychnovoline ( 4 ), 6‐ O ‐nicotinoyltetrahydrocantleyine ( 5 ), 6‐ O ‐(5‐vinylnicotinoyl)tetrahydrocantleyine ( 6 ), racemigerine ( 7 ), 6,7‐epoxyracemigerine ( 8 ), and scaevoline ( 9 ). The structures of the new compounds have been elucidated by their spectral data and confirmed by chemical correlations. Moreover, the absolute configuration of 2 , which had not been previously determined, has been elucidated.
