Homo- and heterocoupling of terminal conjugated enynes: One-pot synthesis of alka-1,7-diene-3,5-diynes and alk-1-ene-3,5-diynes via two types of coupling reaction
Conjugated dienediynes and enediynes with definite geometry- have been prepared in a one-pot manner. This protocol involves two types of coupling reaction, a Suzuki-type coupling and either a Hay coupling or a Cadiot-Chodkiewicz coupling. Thus, the copper
