experimental part, p. 2756 - 2760 (2010/01/21)
A new and highly efficient methodology for the stereocontrolled synthesis of aminodeoxyalditols is described through a dimesylation/intramolecular SN2 nucleophilic substitution ringforming reaction sequence from glucose, mannose, and galactose derivatives

Two isomeric bicyclo4.1.0heptane analogues of the glycosidase inhibitor galacto-validamine, (1R*,2S,3S,4S,5S,6S*)-5-amino-1-(hydroxymethyl) bicyclo4.1.0heptane-2,3,4-triol, have been synthesized in 13 steps from 2,3,4,6-tetra-O-benzyl-d-galactose. The inh
Synthesis and analysis of substrate analogues for UDP-galactopyranose mutase: Implication for an oxocarbenium ion intermediate in the catalytic mechanism

(Chemical Equation Presented) UDP-D-galactofuranose (2), which is essential for both cell growth and virulence in many pathogenic microorganisms, is converted from UDP-D-galactopyranose (UDP-Galp, 1) by the flavin adenine dinucleotide (FAD)-dependent enzyme UDP-galactopyranose mutase (UGM). Here, we report the synthesis of UDP-GalOH (13) and show it as an inhibitor for UGM with a binding affinity similar to that of 1. These results are more consistent with a mechanism involving an oxocarbenium ion intermediate in UGM catalysis.

2,3,4,6-Tera-O-benzyl-hexos-5-uloses derived from D-glucose, D- mannose and D-galactose have been cyclized to cis-diols by a one pot Swerm oxidation/SmI2-mediated pinacol coupling procedure. The effect of the substituent orientation on the diastereoselectivity of the coupling step is examined.

Additions of the γ-alkoxy allylic stannanes (S)-1 and (R)-1 and the racemate (RS)-1 to the threose and erythrose aldehyde derivatives 6 and 15 in the presence of BF3*OEt2 or MgBr2*OEt2 were examined in order to establish stereochemical preferences.It was found that (S)-1 and aldehyde 6 afforded the syn,anti,syn adduct 7 in the BF3-promoted reaction, while (R)-1 and 6 gave the syn,syn,syn adduct 8 under MgBr2 conditions.Likewise, (S)-1 and aldehyde 15 yielded the syn,anti,anti adduct 16 with BF3, whereas (R)-1 and 15 led to the syn,syn,anti adduct 17 with MgBr2.The MgBr2-promoted reactions showed sufficient rate differences between the matched and mismatched stannanes to allow the use of racemic stannane (RS)-1 in just over 2-fold excess, whereupon the matched adducts 8 and 17 were favored by greater than 9:1 over the mismatched adducts.The major adducts 7, 8, 16, and 17 were converted to the hexose derivatives 21, 30/31, 34, and 39 by ozonolysis, selective deprotection, and refunctionalization.Adducts 16 and 17 were dihydroxylated with OsO4-NMO to the deoxyoctose precursors 40/41 and 42/43.
