The present invention relates in general terms to a variously substituted 1, 2, 4-oxadiazol derivative, a process for their preparation, and use thereof as an intermediate in the preparation of indolic alkaloids, including phidianidine B and A.
Two indole alkaloids, phidianidines A (1) and B (2), exhibiting an uncommon 1,2,4-oxadiazole ring linked to the indole system, have been isolated from the marine opisthobranch mollusk Phidiana militaris. The structures of the two metabolites have been elucidated by spectroscopic techniques. Phidianidines exhibit high cytotoxicity against tumor and nontumor mammalian cell lines in in vitro assays.
