Published: January 2015

A concise synthesis of four C-3 fluoro/chloro-D-xylono-δ-lactams 3/4 has been reported. The methodology involves Corey-Link approach with suitably protected 3-oxo-D-gluco-furanose to introduce F/Cl as well as ester/amide functionalities at C-3 of glucose. In next steps, 5,6-O-isopropylidene group was converted to the 5-azido xylosugars that on opening of 1,2-acetonide group, and intramolecular Schmidt-Boyer reaction with TFA/H2O, in one pot, afforded lactams 3/4. Conformational aspect of δ-lactams was studied by the 1H NMR spectroscopy. The halogenated δ-lactams 3/4 showed no inhibition against different glycosidase enzymes.
