Pterogyne nitenes

Two new hexahydroimidazopyrimidines [15, R =-C(Me)=CH2, R = R = H and R = H, R = -C(Me)=CH2, R - -COCH=CMe2] have been characterised by spectral and chemical methods. Additionally, 2,2-dimethyl-acrylamide and two guanidine alkaloids (see Pterogyne nitens) have been shown to be constituents of this species. [Pg.458]

The structures of the guanidine alkaloids 75 - 78 encountered in this study were elucidated with the aid of spectroscopic data especially NMR techniques including DEPT, HETCOR and HMBC techniques. Interestingly, pterogynine (79), which has previously been isolated from Pterogyne nitens [60], was not encountered in this study. [Pg.489]
