  Reductive Amination of Glycosyl Aldoses: Synthesis ofN‐Glycosylated β‐Glycosyl Amino Alcohols and their Enzyme Inhibitory Effect

  摘要：

  Reductive amination of glycosyl aldehydes (la-c, 2) with glycosyl amino esters (3a-c, 4) in the presence of sodium borohydride gave diglycosylated amino esters (5-15) in good yield. N-Glycosyl-glycosylated amino esters were reduced to the respective diglycosyl amino alcohols (16-26) with LiAlH4 in good yield. All the synthesized compounds were studied for their inhibitory effect, if any, against hepatic glucose-6-phosphatase, glycogen phosphorylase, and intestinal brush border membrane alpha-glucosidase; among these compounds 7, 21, and 25 have shown marked inhibition on these enzymes, respectively.
