A convenient zinc-promoted [4+3] cycloaddition of a carbonyl ene-yne with simple dienes was first achieved. This reaction provided an efficient strategy to prepare various cyclohepta[b]furan rings by cascade cycloadditions. Additionally, a multicomponent reaction of dione, alkynal, and diene was also reported, which exhibited a novel strategy for selective creations of C-O bonds and C-C bonds.
首次实现了一种便捷的锌促进的羰基烯炔与简单二烯的[4+3]环加成反应。该反应提供了一种通过串联环加成制备各种环庚并[b]呋喃环的有效策略。此外，还报道了二酮、炔醛和二烯的多组分反应，其展示了一种选择性形成C-O键和C-C键的新策略。
