title: Synthesis of callyberynes A and B, polyacetylenic hydrocarbons from marine sponges.
abstract: [structure: see text] Callyberynes A and B, polyacetylenic hydrocarbons from Callyspongia sp., have been synthesized for the first time using highly convergent approaches based on optimized Cadiot-Chodkiewicz (Alami, Vasella) and sequential Sonogashira cross-coupling reactions.
