LYCOPODIUM ALKALOIDS: PART VIII. NEW ALKALOIDS FROM JAMAICAN LYCOPODIUM SPECIES

Four more alkaloids have been isolated from Lycopodium fawcettii. Lycodine and des-N-methyl-α-obscurine have been found in other Lycopodium species but base L, C 18 H 31 NO 4 , and base R, C 16 H 24 N 2 O 2 , are new. Some transformations of base L are described including its conversion to the previously described base O. An unstable base from L. clavatum has been characterized as the picrate C 15 H 25 NO 3 .C 6 H 3 N 3 O 7 . Further characterization of the two bases fawcettidine (base F) and fawcettimine (base A) is reported.
