✦ Synopsis

Suxmary: Laurenyne, a new chloroacetylene from the red form of the alga Laurencia obtusa has been identified and its crystal structure determined.

Numerous halogenated metabolites have been isolated from red algae of the Lawencia genus mostly terpenes but also a growing family of Cl5 acetylenic cyclic ethers. L. obtusa is widely distributed and in Turkish waters it varies in colour and to some extent in morphology.
