An Efficient Synthesis of Stereodefined Enynes and Dienes via Pd-Catalyzed Reaction of Chloroenynes and Chlorodienes with Grignard Reagents
摘要:
In the presence of PdCl2(PPh(3))(2) and Et(3)N, chloroenynes and chlorodienes react rapidly under mild conditions with various Grignard reagents to give isomerically pure conjugated enynes, dienes, dienynes and trienes in good isolated yields. (C) 1997 Published by Elsevier Science Ltd.
