An efficient and stereoselective synthesis of a chiral precursor of 2-chloro-4-hydroxy-4-alkyl-2-cyclopentenone has been realized by alkylation of a sugar methyl uronate derived from 1, 2-O-isopropylidene α-D-glucose with an acetonyl equivalent, and

Synthesis of silylglycosides of 3-azido-2-deoxy-L-arabino- and ribo-hexopyranoses 4 and 5 has been achieved in 3 steps and 44,6% and 18% overall yields, respectively. The corresponding N-trifluoroacetamido derivatives 9 and 10 were further prepared i

A furo[2,3- c ]pyran-β-D-thymidine nucleoside analog was synthesized from 5′-O-TBDMS-3′-C-allyl-thymidine by 4′-C-hydroxymethylation followed by an electrophilic 6-membered ring annellation. The new bicyclonucleoside was devoid of activity aga

A convenient construction of chiral 4-hydroxy 2-cyclopentenones from α-alkoxy aldehyde 6 derived from sugar is reported. A mechanism is proposed involving imine-enamine equilibrium, then alkylation with 2-alkoxypropenyl iodide followed by a tandem 3

The ectopeptidase gamma-glutamyltranspeptidase (gamma-GT) is overexpressed in myeloid leukemias. Its specific inhibitor, acivicin, was previously shown to induce an inhibitory growth effect associated with an induction of morphological features chara
