The constitution of four new alkaloids (1-4) isolated from a Red Sea sponge, Leucetta chagosensis Dendy, has been established by spectral methods.The compounds are substituted 2-amino imidazoles and substituted imidazolyl 2,4-dioxo-imidazolidinyl amines.
1-Methyl-3-trimethylsilylparabanic acid as an effective reagent for the preparation of N-substituted (1-methyl-2,5-dioxo-1,2,5H-imidazolin-4-YL)-amines and its application to the total synthesis of isonaamidines A and C, antitumor imidazole alkaloids
