Abstract
An unexpected silver triflate-catalyzed tandem reaction of N'-(2-alkynylbenzylidene)hydrazide with ketene through 6-endo-cyclization, [3+2] cycloaddition and rearrangement is reported. This reaction proceeds efficiently to generate the molecular complexity with the formation of four bonds in a one-pot procedure.
摘要
本文报道了 N'-(2-炔基苯亚甲基)腙与烯酮在银 triflate 的催化下通过 6-endo-环化、[3+2]环加成和重排的串联反应。该反应在一锅法中高效进行，以形成四个键的方式生成具有分子复杂性的产物。
