Chemoenzymatic synthesis of novel adenosine carbanucleoside analogues containing a locked 3′-methyl-2′,3′-β-oxirane-fused system
摘要:
Starting from a readily available enantiopure building block, a straightforward enantioselective approach to 3 '-methyl-2 ',3 '- beta-oxirane-fused carbanucleosides bearing adenosine analogues is detailed. The key steps in the syntheses involved a lipase-catalyzed regioseleclive monoacylation of a diol to obtain the key intermediate and direct coupling of this key intermediate with diversely substituted purine nucleobases under Mitsunobu reaction conditions providing only the N-9 target molecules.

viral pathogens. None of the new compounds had significant antiviral activity at a concentration of 100 µg˙mL-¹, which was the highest concentration tested. stereoselective synthesis- azides - carbocyclic nucleosides - nucleobases - antiviral agents
Enantiopure ethyl (1 S,4 R)-4-hydroxy-2-methylcyclopent-2-ene-1-carboxylate, readily obtained by enzymatic kineticresolution of the corresponding racemic derivative, provided a convenient starting building block for an 11-step chiral preparation of (-)-3′-methylaristeromycin with 23% overall yield.

synthesized via the SN 2 displacement of a key triflate, which was prepared from a readily available enantiopure building block in eight steps. The synthesized compounds were evaluated as potential antiviral agents against important viruses. Only the 2,6-diaminopurine derivative exhibited moderate activity against vesicular stomatitis virus.
通过关键三氟甲磺酸酯的 SN 2 置换合成了一系列 3'-甲基支化和嘌呤修饰的马兜铃霉素类似物,该三氟甲磺酸酯由易于获得的对映体纯结构单元分八步制备。合成的化合物被评估为针对重要病毒的潜在抗病毒剂。只有 2,6-二氨基嘌呤衍生物对水疱性口炎病毒表现出中等活性。

This paper describes the racemic and stereoselective synthesis of novelconformationally locked 3'-methyl-2',3'-oxiranefused carbocyclic nucleosides (nucleosides numbering). The key step is the direct coupling of an alcohol bearing the 1-methyl-6-oxabicyclo[3.1.0]hexane scaffold with diversely substituted purine nucleobases under Mitsunobu reaction conditions providing only the N 9 target molecules
