Ta daa: The title reaction proceeds under essentially neutral reaction conditions at ambient temperature with a taddol‐based phosphoramidite ligand L* allowing the creation of indanes with quaternary stereogenic centers in high enantiomeric excess (see scheme; Tf=trifluoromethanesulfonyl, DMAc=dimethylacetamide).
Ta daa:标题反应在室温下基本基于中性反应条件下,使用基于taddol的亚磷酰胺配体L *进行,从而以对映体过量的形式生成具有季立体异构中心的茚满(见方案; Tf =三氟甲磺酰基,DMAc =二甲基乙酰胺)。
