Synthesis of novel 3′,4′-seco analogues of didehydro dideoxy nucleosides as potential antiviral agents
摘要:
Novel acyclo analogues (13,14) of didehydro dideoxy adenosine (d4A) lacking C-3'-C-4' bond were synthesized as potential anti-HIV agents. The key step involves the bromination of unsaturated isomer 6 with NBS in mono protected ethylene glycol leading to 3',4'-seco-2'-bromo-3'-hydroxl compound 11a. Activation of 3'-hydroxy group and reductive elimination of vicinal bromo tosylate gave 13 which on deprotection was converted into the target molecule 14.

9-(3-Phosphonomethoxyprop-1-en-yl)adenine (Z)- and (E)-isomers were synthesized. The stereoselectivity of double bond formation was studied by variation of sulfonyl groups. The resulting phosphonates exhibited a moderate antiherpetic activity in a culture of Vero cells infected with herpes simplex type 1 virus. The Z-isomer was shown to be more effective inhibitor of virus reproduction in the case
