Palladium-catalyzed coupling of heteroaromatic triflates with acetylene and its application for a dynemicin a intermediate
摘要:
An acetylene moiety was introduced to a carbonyl carbon of amide group via its triflate in the presence of palladium catalyst, The reaction proceeded smoothly under mild conditions. Utilizing this methodology, a model compound of dynemicin A bearing acetylene group was synthesized.
