Abstract

Examination of the red alga Plocamium cartilagineum (L.) Dixon collected along the Antarctic Peninsula yielded several new cyclic halogenated monoterpenes. The structures of a 2,4-dichloro-trans-1-chloro-vinyl-1-methyl-5-methylene-cyclohexane, a 2-chloro-4-bromo-trans-1-chlorovinyl-1-methyl-5-methylene-cyclohexane, a 2-chloro-trans-1-chlorovinyl-1-methyl-5-chloromethyl-4-cyclohexene, and a 2,5-dichloro-4-bromo-trans-1-chlorovinyl-1-methyl-5-bromomethyl-cyclohexane are described. The structures were determined by spectroscopic methods and chemically related to the halogenated monoterpene violacene.
