Abstract
Reductive amination of glycosyl aldehydes (1a–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 α‐glucosidase; among these compounds 7, 21, and 25 have shown marked inhibition on these enzymes, respectively.
