    摘要: Pharmaceutical prodrug compositions are provided comprising azide derivatives of drugs which are capable of being converted to the drug in vivo. Azide derivatives of drugs having amine, ketone and hydroxy substituents are converted in vivo to the corresponding drugs, increasing the half-life of the drugs. In addition azide prodrugs are often better able to penetrate the blood-brain barrier than the corresponding drugs. Especially useful are azide derivatives of cordycepin, 2′-F-ara-ddI, AraA, acyclovir, penciclovir and related drugs. Useful azide prodrugs are azide derivatives of therapeutic alicyclic amines, ketones, and hydroxy-substituted compounds, including aralkyl, heterocyclic aralkyl, and cyclic aliphatic compounds, where the amine or oxygen moiety is on the ring, or where the amine or oxygen moiety is on an aliphatic side chain, as well as therapeutic purines and pyrimidines, nucleoside analogs and phosphorylated nucleoside analogs.

    摘要: An asymmetric process for the preparation of enantiomerically pure .beta.-L-(-)-1,3-oxathiolane-nucleosides that includes the initial preparation of the key chiral intermediates (2R,5R) and (2R,5S)-5-(O-protected)-2-(protected-oxymethyl)-1,3-oxathiolane from 1,6-thioanhydro-L-gulose. The 2R,5(R,S)-5-(O-protected)-2-(protected-oxymethyl)-1,3-oxathiolane is condensed with a desired heterocyclic base, typically a purine or pyrimidine base, to provide the product nucleoside. The synthesis can be used to prepare the pharmaceutically important compound, .beta.-L-(-)-1-[(2.beta.,4.beta.)-2-(hydroxymethyl)-4-(1,3-thioxolane)]cytosine (.beta.-L-(-)BCH-189).
