摘要：

Treatment of the lithium enolate derived from homochiral (S)-[(eta5-C5H5)Fe(CO)(PPh3)COCH3 5 with benzyne afforded the homochiral phenylacetyl complex (S)-[(eta5-C5H5)Fe(CO)(PPh3)COCH2Ph] 4. Treatment of the lithium enolate derived from 4 with ClCH2OCH2Ph furnished the homochiral alpha-substituted complex (S,S)-(-)-[(eta5-C5H5)-Fe(CO)(PPh3)COCH(CH2OCH2Ph)Ph] 4 (d.e. > 98%), which on decomplexation and debenzylation afforded (S)-(-)-methyl tropinate (S)-2 (e.e. > 98%).
