| Abstract: | Mono- and di-N-alkylated derivatives of 1,3,4,6-tetra-O-acetyl-2-amino-2-deoxy-beta-D-glucose (alkyl=methyl, ethyl, propyl, butyl, pentyl, hexyl, benzyl) were synthesised by the reductive alkylation of per-O-acetyl-d-glucosamine. (N-ethyl, N-propyl, N-butyl, N-pentyl and N-hexyl)-1,3,4,6-tetra-O-acetyl-2-amino-2-deoxy-beta-D-glucoses were deacetylated in order to attempt an enzymatic phosphorylation. All products were characterised by means of IR, NMR and MS spectra. N-Ethyl- and N-pentyl-d-glucosamines were found to exhibit weak antifungal activity. |
