Ag(I)-catalyzed asymmetric 1,3-dipolar cycloaddition of azomethine ylides. This methodology shows good functional-group tolerance, delivering an array of synthetically valuable cyclopentene-1,3-diones with excellent stereoselectivity and generally high resolution efficiency (s = 48–226) accompanied by the biologically important fused pyrrolidine derivatives. Notably, this strategy allows facile access to the key
通过Ag(I)催化的偶氮甲亚胺的不对称1,3-偶极环加成反应,已经开发出一种有效的动力学拆分消旋环戊烯-1,3-二酮。这种方法显示出良好的官能团耐受性,提供有价值的合成环戊烯-1,3-二酮的阵列具有优异的立体选择性和通常高分辨率效率(小号伴随生物学上重要的稠吡咯烷衍生物= 48-226)。值得注意的是,该策略允许轻松地获得关键中间体,以合成(+)-madindoline A和B。
