An Improved Synthesis of 2-Acetamido-2-deoxy-D-gluconohydroximolactone (PUGNAc), A Strong Inhibitor ofβ-N-Acetylglucosaminidases
摘要:
O-(2-Acetamido-3,4:6-tri-O-acetyl-D-glucopyranosylidene)amino N-phenylcarbamate (1), an established inhibitor of beta-N-acetylglucosaminidases, has been prepared by an improved six-step synthesis from N-acetyl-D-glucosamine.

inhibitor PUGNAc was synthesized and two isomers based on the E and Z stereochemistry of the oxime moiety were separated, defined, and tested for activity. Several lines of evidence were examined in an effort to define the correct stereochemical assignments of each form of PUGNAc. The ability of the Z stereoisomer to undergo the Beckmannrearrangement was ultimately the most definitive proof. It was determined
