Synthesis of novel chiral phosphines from α,α-trehalose

New disaccharide chiral phosphines, such as 4,6-O-benzylidene-2- (diphenylphosphino)-2-deoxy-α-D-altropyranosyl-(1,1)-4,6-O-benzylidene-2- (diphenylphosphino)-2-deoxy-α-D-altropyranoside 1 and 2-(diphenylphosphino)- 2-deoxy-4,6-O-isopropylidene-α-D-altropyranosyl-(1,1)-2-(diphenylphosphino)- 2-deoxy-4,6-O-isopropylidene-α-D-altropyranoside 9, were prepared from α,α-trehalose. We also succeeded in the synthesis of polyhydroxy chiral diphosphine 2-(diphenylphosphino)-2-deoxy-α-D-altropyranosyl-(1,1)-2- (diphenylphosphino)-2-deoxy-α-D-altropyranoside 5 by deprotection of isopropylidene groups.
