Abstract
Paranitrophenyl 2-O-acetyl, and 2,3-di-O-acetyl-β-d-glucopyranoside (VI, VII) were synthesized in order to investigate the effect of the substitution of the amide-nitrogen of the substrate by oxygen on the N-acetyl-β-d-glucosaminidase hydrolysis. Paramethoxybenzylidene was used as an O-blocking group for the preparation, and it was found that this blocking group could be easilly removed without the destruction of p-nitrophenyl glycoside. The evidence that VI could not be hydrolysed with this enzyme indicated the essential requirement of the amide-nitrogen of the substrate for the enzyme action.
