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(PPh3)2Cl2]) as catalyst was also carried out with success.
一系列新炔属化合物的合成1 - 7,最近从真菌中分离Eutypa LATA,进行说明。关键步骤是受保护的芳基卤化物与炔属链之间的偶联反应,即乙炔化亚铜(流程1)。还成功地使用了双(三苯基膦)二氯化钯([Pd(PPh 3)2 Cl 2 ])作为催化剂,效率更高。
