  Stereoselective synthesis of phosphoramidate α(2-6)Sialyltransferase transition-State analogue inhibitors

  摘要：

  The asymmetric synthesis of novel, potent phosphoramidate alpha(2-6)sialyltransferase transition-state analogue inhibitors such as (R)-9 (K-i - 68 muM) is described, via condensation of cytidine phosphitamide 6 with key chiral, non-racemic alpha-aminophosphonates, prepared in > 98 % ee by Mitsunobu azidation followed by Staudinger reduction of the corresponding chiral, non-racemic alpha-hydroxyphosphonates.

  Chiral, non-racemic α-hydroxyphosphonates and phosphonic acids via stereoselective hydroxylation of diallyl benzylphosphonates

  摘要：

  Chiral, non-racemic alpha-hydroxyphosphonates have been prepared in high enantiomeric excess (96-98% ee), via stereoselective oxaziridine-mediated hydroxylation of diallyl benzylphosphonates. The enantiomeric purity and absolute configuration of the alpha-hydroxyphosphonates was established from H-1 and P-31 NMR spectroscopy of the (S)-O-methylmandelate esters. Deprotection of the diallyl alpha-hydroxyphosphonates under neutral conditions furnished the corresponding free phosphonic acids, retaining a high degree of stereochemical purity (90 to >98% ee).
