We report a short synthetic route that provides optically active 2-substituted hexahydro-1H-pyrrolizin-3ones in four steps from commercially available Boc (tert-but(oxy)carbonyl))-protected proline. Diastereoisomers (Γ)-11 and (Γ)-12 were assembled from the proline-derived aldehyde (Γ)-8 and ylide 9

A series of new optically active aromatic polyimides containing axially dissymmetric 1,1 -binaphthalene-2,2-diyl units were prepared from optically pure ( R)-(/)-or (S)-(0)-2,2-bis(3,4-dicarboxyphenoxy)-1,1 -binaphthalene dianhydrides and various aromatic diamines via a conventional two-step procedu
