A robust transition-metal-free one-step strategy for the synthesis of ynamides from sulfonamides and (Z)-1,2-dichloroalkenes or alkynyl chlorides is presented. This method is not only effective for internal ynamides but also amenable for terminal ynamides. Various functional groups, even the vinyl moiety, are compatible, and thus, this strategy offers the opportunity for further functionalization.
提出了一种强大的无过渡金属的一步法,用于从磺酰胺和(Z)-1,2-二氯烯烃或炔基氯化物合成乙酰胺。该方法不仅对内部的神经酰胺有效,而且对末端的神经酰胺也适用。各种官能团,甚至乙烯基部分都是相容的,因此,该策略提供了进一步官能化的机会。
