An unprecedented Zn-promoted selective cleavage of vinyl azides for the synthesis of 4-substituted quinolines is developed. In this conversion, vinyl azides function as a dual synthon via C═C and C–N bond cleavage with two C═C bonds and one C═N bond formation in a one-step manner. The reaction is appreciated for its readily accessible substrates, high step economy, mild conditions, and use of air as
开发了前所未有的锌促进乙烯基叠氮化物选择性裂解的方法,用于合成4-取代的喹啉。在这种转化中,叠氮化乙烯通过一步一步的C═C和C–N键断裂与两个C═C键和一个C═N键形成,起到双重合成子的作用。该反应因其易于接近的底物,高步骤经济性,温和条件以及使用空气作为唯一氧化剂而受到赞赏。
