Abstract

Two new halogenated sesquiterpenes, (8__β__)‐10‐bromo‐3‐chloro‐2,7‐epoxychamigr‐9‐en‐8‐ol (1) and 2‐bromo‐3‐chlorobisabola‐7(14),11‐diene‐6,10‐diol (3), and one new phytol‐derived diterpene, 2,3‐epoxyphytyl acetate (4), along with cis‐ and trans‐1‐methylcyclohexane‐1,4‐diol (5 and 6) which were isolated from a natural source for the first time but have been previously synthesized, were isolated from the marine red alga Laurencia composita and characterized. In addition, a known sesquiterpene, pacifenediol (2), and the known furanone derivative 7 were also identified. Their structures were established by NMR and mass spectroscopic methods.
