A practical approach for the synthesis of cyclic phenyl hexayne is demonstrated through a one-pot deprotection/transformation of magnesium acetylide into a copper acetylide/Sonogashira coupling procedure, followed by dephosphination, Hay coupling, desilylation, and Eglinton coupling. This approach avoids tedious synthetic routes and harsh reaction conditions and affords the product in 41% yield.
