A Novel Type of Spironucleosides: 2′,5′-O-bis-TBDMS Uridine-3′-spiro-3′-isoxazolidin-5′-one and Its Thymidine Congener
摘要:
TSAO analogues, 2',5'-O-bis-TBDMS uridine-3'-spiro-3 ''-isoxazolidin-5 ''-on (9) and its thymidine congener 10, as well as model spiro sugar derivatives (3 and 4) have been prepared from the corresponding nitrones through a stereospecific tandem nucleophilic attack. Compounds 9 and 10 which are bioisosters of TSAO-U and T respectively but which lack an amino group on the spiro ring, were found inactive against both HIV-1 and HIV-2.
