A series of isonucleoside 5'-triphosphates were synthesized via a rapid and efficient method. The structures of the triphosphates (8a-8d) were characterized by (PNMR)-P-31 and TOF-MS.
Studies on the synthesis and biological activities of 4′-(R)-hydroxy-5′-(S)-hydroxymethyl-tetrahydrofuranyl purines and pyrimidines
摘要:
A series of 4'-(R)-hydroxy-5'-(S)-hydroxymethyl-tetrahydrofuranyl purines and pyrimidines were synthesized by the reaction of 3,4-epoxy-5-(S,trans)-dimethoxymethyl-tetrahydrofuran and nucleobases under the catalysis of potassium tert-butoxide and 18-crown-6. Compounds 6a, 6c and 7b have shown significant inhibition on the growth of HL-60 cells. The phosphotriester and phosphodiester of isonucleoside 8a-d were synthesized and cytotoxic activities were reported. The conformation of isonucleosides in solution was studied by H-1 NMR.

L-Isonucleosides 17 and 19 were stereoselectively synthesised from (S)-glycidol by two different procedures. The key step was the synthesis of a chiral dihydrofuran which was carried out by oxidation/elimination of 8 and by ring-closing metathesis of diene 10. The procedure can be applied to the synthesis of both enantiomers. (C) 2003 Elsevier Science Ltd. All rights reserved.
