  • Carbanucleoside synthesis and novel intermediate compounds useful therein
    Patent number: 8658792
    Abstract: Anti-virally active carbanucleosides such as entecavir are prepared by a process which utilizes, throughout the synthesis, an aromatic protectant group for the hydroxyl and the alkyl hydroxy groups of the starting material, removed as the final step of a multi-step synthesis. Such protectant groups yield intermediates which are solid and therefore easily purified at various stages of the process, for an economical and relatively fast process for synthesizing the final product.
    Type: Grant

    Date of Patent: February 25, 2014
    Assignee: Alphora Research Inc.
