Abstract
Abstract The synthesis of a series of novel acetylenic compounds 1–7, isolated recently from the fungus Eutypa lata, is described. The crucial step is the coupling reaction between a protected aryl halogenide and the acetylenic chain as a cuprous acetylide (Scheme 1). A more efficient method using bis (triphenylphosphine) palladium dichloride ([Pd (PPh 3) 2 Cl 2]) as catalyst was also carried out with success.
