A new glucose-based C2-derivatized colorimetric chemo-sensor (L1) has been synthesized by a one-step condensation of glucosamine and 2-hydroxy-1-naphthaldehyde for the recognition of transition metal ions. Among the eleven metal ions studied, v

We report the synthesis of new persulfide-spacer N-substituted-2- azetidinone-D-glucosamine in an attempt to potentially provide new antibiotics. The Schiff base ligands considered for this study were derived from D-glucosamine and 2-hydroxybenzaldehyde, 4-methoxy-benzaldehyde, cinnamaldehyde, 4-chlorobenzaldehyde, and 4-hydroxy-3-methoxy-benzaldehyde. Staudinger [2+2] cycloaddition of benzyloxyacetyl chloride to the newly reported per-O-allyl-N-substituted benzylidene-2-deoxy - D-glucosamine provided the sugar-based monocyclic -lactams in moderate yields. Radical addition of 2-mercaptoethanol catalyzed by azobisisobutyronitrile to the per-O-allyl-N-substituted-2-azetidinone-D-glucosamine led to the corresponding persulfide-spacers in good yields. All new compounds were characterized by spectroscopic and spectrometric methods. The scanning electron microscopy image of 1,3,4,6-tetra-O-[3-(hydroxythioethyl)-propyl]-2-deoxy-2-N-[(3-benzyloxy-4-(4- chloropenyl)-2-azetidinone] - D-glucopyranoside, as a representative example, demonstrated a super hydrophobic layer formed via highly organized thioether spacers on gold as the adsorbate system through the formation of sulfur-gold bonds. The reported glucosides showed a moderate antifungal activity against Candida albicans while being slightly to moderately active against gram-positive and gram-negative bacteria used in this investigation at a concentration of 1 mg/mL dissolved in dimethyl sulfoxide.
