Bicyclic-5-hydroxy-2-pyrrolidinones (2a-f) were synthesized with high enantioselectivity by the reduction of meso-cyclic-1,2-dicarboximides (1a-f) with lithium aluminum hydride (LiAlH4)-methanol(MeOH)-1,1-bi-2-naphthol complex (BINAL-H).Treatment of 2a-f with triethylsilane (Et3SiH) and trifluoroacetic acid (CF3CO2H) gave optically active 2-pyrrolidinones (3a-f) in quantitative yields.For the absolute configuration correlation, 2a-d were converted into known lactones (4a-d).
