Citharoxazole (1), a new batzelline derivative featuring a benzoxazole moiety, was isolated from the Mediterranean deep‐sea sponge Latrunculia (Biannulata) citharistae Vacelet, 1969, together with the known batzelline C ( 2 ). This is the first chemical study of a Mediterranean Latrunculia species and the benzoxazole moiety is unprecedented for this family of marine natural products. The structure was mainly elucidated by the interpretation of NMR spectra and especially HMBC correlations. Copyright © 2011 John Wiley & Sons, Ltd.
