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

Abstract

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, C18H31NO4, and base R, C16H24N2O2, 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 C15H25NO3.C6H3N3O7. Further characterization of the two bases fawcettidine (base F) and fawcettimine (base A) is reported.
