Synthesis of the chiral auxiliary 1,3:4,6-di-O-benzylidene-2,5-dideoxy-2,5-imino-D-iditol
摘要:
L-Mannitol 5, the precursor of the the C-2-symmetrical auxiliary 3B, was prepared in high yield by heterogeneous reduction of L-mannonic-gamma-lactone 4. The auxiliary 3B could be used for stereoselective photochemical synthesis of the L-proline derivative 2B. Copyright (C) 1996 Elsevier Science Ltd
