(2R,3S,5S)-2-Acetoxy-3-fluoro-5-(p-toluoyloxymethyl)tetrahydrofuran: a key intermediate for the practical synthesis of 9-(2,3-dideoxy-2-fluoro-β-d-threo-pentofuranosyl)adenine (FddA)
摘要:
A highly efficient synthesis of (2R,3S,5S)-2-acetoxy-3-fluoro-5-(p-toluoyloxymethyl)tetrahydrofuran (2a) was developed. As a key intermediate, 2a was effectively applied to the synthesis of 9-(2,3-dideoxy-2-fluoro-beta -D-threo-pentofuranosyl)adenine (FddA), thus, providing a practical synthesis approach to FddA.

The photochemical [2 + 2] cycloaddition of chiral 3-chloro and 3-fluoro-5-hydroxymethyl-2(5H)-furanone to ethylene and acetylene has been studied. The effect of the halogen atom on the chemical yield and facial diastereoselectivity of the cycloaddition process has been evaluated. From the major anti cycloadducts, practical syntheses of several purine cyclobutane and cyclobutene-fused nucleosides containing

We studied the structure-activity relationships of a series of 2'-fluoro-2',3'-unsaturated D-nucleosides against HIV-1 in human peripheral blood mononuclear (PBM) cells. The target compounds 10-21 and 28-33 were prepared by N-glycosylation of the acetate 4, which was readily prepared from 2,3-O-isopropylidene-D-glyceraldehyde in five steps. Among the newly synthesized nucleosides, 2-amino-6-chloropurine
