  Synthèse stéréosélective de la girolline

  摘要：

  Desaminogirollines syn 2'S,3'S and 2'R,3'R have been prepared from N1-camphosulfonamide 4-carboxaldehyde imidazole and their diastereoisomeric derivatives have been separated. The stereoselective synthesis of chiral natural girolline has been achieved from D(-)arabinose: this ose is condensed with formamidine acetate to obtain a 4(5)-[1',2',3'-trihydroxypropyl]-imidazole; the side-chain is chlorinated before being aminated via an azido compound and the 2-amino group of girolline is obtained by rhodium catalytic reduction of the 2-diazo derivative.

  New C2 symmetrical and semisymmetrical substituted imidazolium ribonucleoside. Imidazolic nucleosides analogues

  摘要：

  New C-2 symmetrical imidazolium ribonucleosides have been synthesized. The silyl Hilbert Johnson-Vorbrugen method was used. Subsequent coupling of trimethylsilylimidazole with the peracylated D-ribofuranose 1, followed by removal of the protecting groups, afforded 1,3-bis(beta-D-ribofuranosyl)imidazolium 7 and 1-(beta-D-ribofuranosyl)imidazole 8. In a similar synthetic sequence, 4(5)-substituted bis-ribofuranosylimidazolium 14 was also prepared, For the selective preparation of the monoglycosylated imidazole 15, the classical method starting from 2,3,5-tri-O-benzoyl-D-ribofuranosyl bromide in acetonitrile and using Hg(CN)2 was employed. These new base modified nucleosides were devoid of activity against HIV and cytotoxicity. Copyright (C) 1996 Elsevier Science Ltd.
