  • Remarkable β-Selectivity in the Synthesis of β-1-<i>C</i>-Arylglucosides:  Stereoselective Reduction of Acetyl-Protected Methyl 1-<i>C</i>-Arylglucosides without Acetoxy-Group Participation

    [GRAPHICS]An efficient and practical process to generate beta-C-arylglucoside derivatives was achieved. The process described involves Lewis acid mediated ionic reduction of a peracetylated 1-C-aryl methyl glucoside derived from the addition of an aryl-Li to selectively protected delta-D-gluconolactone. The reduction of the 2-acetoxy-1-C-oxacarbenium ion intermediates proceeds with a high degree of selectivity to give beta-C-arylglucosides without 2-acetoxy group participation. Furthermore, during the reduction process we also identified an unprecedented critical role of water. By changing from the usual benzyl ether protecting groups because of cost and chemical compatibility concerns, the new process is made additionally efficient and highly selective.
