efficient syntheses of dibenzocyclooctadienediyne 1 were developed employing known reactions, which utilize commercially available reagents. Both methods are an improvement on known syntheses resulting in 41% and 43% overall yields. The latter method also offers an efficient synthesis of dibenzocyclooctateraene 9, which is one of the key reagents now commercially unavailable.
二苯并环辛二烯二炔 1 的两种有效合成方法是使用已知反应开发的,这些反应利用市售试剂。这两种方法都是对已知合成的改进,总产率分别为 41% 和 43%。后一种方法还提供了二苯并环辛四烯 9 的有效合成,这是目前商业上无法获得的关键试剂之一。
