Abstract Two types of cyclic polythiophospholipid conjugated with N1 -(2-fu ran idyl)-N3-(2-hydroxyethyl)-5-fluorouracil were synthesized. The hexaethyl phosphoroustriamide, activated by a catalytic amount of iodine, was used as the phosphorylating reagent in a one-pot reaction resulting in a number of novel phospholipid-drug conjugates.

N3-Hydroxyethyltegafur (3) was synthesized in 91.0% yield under a new condition. A series of novel fatty acid esters of 3 were synthesized. These fatty acid-nucleoside conjugates have shown cytotoxicities against Ec9706 cells and A549 cells, and the structure activity relationship was discussed. (c) 2007 Elsevier Ltd.

The synthesis of phospholipid conjugates of N-1-(2-furanidyl)-N-3-(2-hydroxyethyl)-5-fluorouracil is reported. The strategy for the synthesis is using hexaethylphosphorous triamide, activated by a catalytic amount of iodine, as the phosphorylating reagent in a one-pot reaction resulting in a number of new types of phospholipid-drug conjugates.

A series of novel phosphoramide-tegafur derivatives containing gamma-aminopropyl silatrane were synthesized Via the condensation reactions of phosphoryl dichloride with N-1-(2-furanidyl)-N-3-(hydroxyethyl)-5-fluorouracil, followed by condensation with gamma-aminopropyl silatrane. The structures of the products were confirmed by H-1 NMR, P-31 NMR, IR, MS, and elemental analysis. The results of preliminary bioassay showed that the new compounds had an inhibition effect against HCT-8 and Bel-7402 cell lines.
Synthesis of Novel Optically Active Cyclic Phospholipid Conjugates of Tegafur and Uridine Starting From L-Serine
Starting from L-serine, cyclic phospholids 2,3 and 4 were synthesized and successfully separated in the form of pure diastereomer. Their configurations were discussed and assigned according to their NMR spectra data. The asymmetric induction effects were also observed in two phosphorylation cyclizations.
