The enantioselective nucleophilic substitution of (±)-2β-acetoxy-4aβ-methyl-2,3,4,4a,5,6-hexahydronaphthalene with dimethyl malonate anion was performed in the presence of palladium-chiral ligand catalysts to give optically active 2-di(methoxycarbonyl)methyl-4a-methyl-2,3,4,4a,5,6-hexahydronaphthalenes.
在钯手性配体催化剂存在下,用丙二酸二甲酯阴离子对(±)-2β-乙酰氧基-4aβ-甲基-2,3,4,4a,5,6-六氢萘进行了对映选择性亲核取代,得到了具有光学活性的 2-二(甲氧基羰基)甲基-4a-甲基-2,3,4,4a,5,6-六氢萘。
