Abstract

A highly efficient one-pot construction of optically active 1,1'-spirobi[indan-3,3'-dione] derivative (up to 80% ee) has been achieved by exploiting the double intramolecular C-H insertion reaction of dimethyl 2,2'-methylenebis(alpha-diazo-beta-oxobenzenepropanoate) under the influence of dirhodium(II) tetrakis[N-phthaloyl-(R or S)-tert-leucinate] as a catalyst.

摘要

通过利用2,2'-亚甲基双(α-重氮-β-氧代苯丙酸甲酯)在四[ N-邻苯二甲酰基-(R或S)-叔亮氨酸]二铑(II)作为催化剂的影响下的双分子内C-H插入反应,实现了光学活性1,1'-螺双[茚满-3,3'-二酮]衍生物的高效一锅法构建(对映体过量高达80%)。
