    摘要： A series of novel compounds showing anticonvulsant, chemical countermeasure(s), and analgesic activities is described. Such pharmaceutically active compounds may also show utility in the treatment of other central nervous system (“CNS”) diseases and disorders, such as anxiety, depression, insomnia, migraine headaches, schizophrenia, Parkinson's disease, spasticity, Alzheimer's disease, and bipolar disorder. Furthermore, such compounds may additionally find utility as analgesics (e.g., for the treatment of chronic or neuropathic pain) and as neuroprotective agents useful in the treatment of stroke(s), chronic neurodegenerative diseases (such as Alzheimer's disease and Huntington's disease), and/or traumatic brain and/or spinal cord injuries. Moreover, these/such compounds may also be useful in the treatment of status epilepticus and/or as chemical countermeasures.

    摘要： This application provides a process for preparing enantiomerically pure β-D-dioxolane nucleosides. In particular, a new synthesis of (−)-DAPD, suitable for large scale development, is described. In one embodiment the invention provides a process for preparing a substantially pure β-D- or β-L-1,3-dioxolane nucleosides comprising a) preparing or obtaining an esterified 2,2-dialkoxy ethanol; b) cyclizing the esterified 2,2-dialkoxy ethanol with glycolic acid to obtain a 1,3-dioxolane lactone; c) resolving the 1,3-dioxolane lactone to obtain a substantially pure D- or L-lactone; d) selectively reducing and activating the D- or L-chiral lactone to obtain a substantially pure D- or L-1,3-dioxolane; e) coupling the D- or L-1,3-dioxolane to an activated and/or protected purine or pyrimidine base; and f) optionally purifying the nucleoside to obtain a substantially pure protected β-D- or β-L-1,3-dioxolane nucleoside.
