A new, catalytic enantioselective route to 3-arylindan-1-ones, versatile intermediates for the synthesis of a number of bioactive and pharmaceutically interesting molecules, was developed by exploiting the chiral dirhodium(II) complex-catalyzed intramolecular C-H insertion reaction of α-diazo-β-ketoesters as a key step. Dirhodium(II) tetrakis]N-phthaloyl-(S)-tert-leucinate], Rh 2 (S-PTTL) 4 , proved
通过利用手性二铑 (II) 络合物催化的 α- 分子内 CH 插入反应,开发了一种新的催化对映选择性 3-arylindan-1-ones 的催化途径,该途径是用于合成许多生物活性和药学上有趣的分子的通用中间体。重氮-β-酮酯作为关键步骤。Dirhodium (II) tetrakis]N-phthaloyl-(S)-tert-leucinate], Rh 2 (S-PTTL) 4 被证明是该过程的首选催化剂,提供高达 72% ee 的对映选择性。
