1,6-Dipolar cycloadditions represent a valuable strategy for the rapid construction of medium-sized rings. Herein, we describe the concept for the design of 1,6-dipoles that bypasses the regioselectivity. Through the introduction of an amino group into Morita–Baylis–Hillman (MBH) carbonates, unprecedented [6 + 2] dipolar cycloadditions were accurately developed with Cs2CO3, efficiently delivering a
1,6-偶极环加成是快速构建中等大小环的一种有价值的策略。在此,我们描述了绕过区域选择性的 1,6-偶极子的设计概念。通过在 Morita-Baylis-Hillman (MBH) 碳酸酯中引入氨基,使用 Cs 2 CO 3准确开发了前所未有的 [6 + 2] 偶极环加成,在温和条件下有效地提供了一系列苯二氮卓类化合物。计算研究使人们对这种反应有了更深入的了解。
