  Regioselective cleavage of the bis-benzylidene acetal of d-mannitol under oxidative and reductive conditions: a new approach to C2-symmetric chiral ligands

  摘要：

  A highly regioselective oxidative cleavage of 1,3:4,6-di-O-benzylidene-D-mannitol was carried out using NBS and the resultant product was readily converted to the Q-symmetric chiral ligand, (R,R)-3,4-dihydroxy-1,5-hexadiene. On the other hand, reductive cleavage of 1,3:4,6-di-O-benzylidene-D-mannitol was achieved in a highly regioselective manner using BF(3)center dot OEt2 and Et3SiH to give a highly functionalized benzyl ether, which was converted to a synthetically useful C-2-symmetric bis-amino alcohol derivative.

  Synthesis of C 2 -symmetric guanidino-sugars as potent inhibitors of glycosidases

  摘要：

  A series of enantiomerically pure C-2-Symmetric guanidino-sugars was synthesized from D-mannitol. The first method described involves direct opening of a bis-epoxide by guanidine, whereas the second one deals with a mercury-catalyzed transformation of a cyclic thiourea into a N,N,N"-trisubstituted guanidine as a key step. The biological activity of these compounds towards several glycosidases has been evaluated. One of them (5) was found to selectively inhibit alpha-L-fucosidase of bovin kidney (2.8 mu M).

• Synthesis of enantiopure bis-aziridines, bis-epoxides, and aziridino-epoxides from d-mannitol
  作者：Devarajulu Sureshkumar、Susama Maity、Srinivasan Chandrasekaran

  日期：2006.10

  A practical synthesis of enantiopure bis-aziridines 11 and 15, bis-epoxides 12 and 17, and aziridino-epoxides 27 and 30 is reported using inexpensive D-mannitol as the starting material. The key transformation involves the reductive cleavage of bis-benzylidene acetal 3 to form dimesylate 4, which was further converted to monoazides and diazides followed by reduction, mesylation, and cyclization to furnish the required compounds in good yields.
