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-benzyl

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 C2-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?OEt2 and Et3SiH to give a highly functionalized benzyl ether, which was converted to a synthetically useful C2-symmetric bis-amino alcohol derivative.
Synthesis of C2-symmetric guanidino-sugars as potent inhibitors of glycosidases
Le Merrer, Yves,Gauzy, Laurence,Gravier-Pelletier, Christine,Depezay, Jean-Claude
, p. 307 - 320 (2007/10/03)
A series of enantiomerically pure C2-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 α-L-fucosidase of bovin kidney (2.8 μM).

Synthesis of C2-symmetrical cyclic guanidino-sugars from D-mannitol
Gauzy, Laurence,Le Merrer, Yves,Depezay, Jean-Claude
, p. 402 - 404 (2007/10/03)
An efficient method for the synthesis of C2-symmetrical cyclic guanidino-sugars has been developed from 1,2:5,6-dianhydro-3,4-O-methylethylidene-D-mannitol or L-iditol.
