Abstract New highly constrained chiral C 1-1,1′-bisisoquinoline ligands were examined in the enantioselective conjugate addition of Grignard reagents to cyclohexenone and cyclopentenone. The desired 1,4-adducts were obtained in excellent yield and moderate enantiomeric excess (up to 35%). GRAPHICAL ABSTRACT
摘要 在格氏试剂与环己烯酮和环戊烯酮的对映选择性共轭加成中,研究了新的高度受限的手性 C 1-1,1'-双异喹啉配体。以极好的收率和适度的对映体过量(高达 35%)获得了所需的 1,4-加合物。图形概要
