  • Patent number: 6005097
    Abstract: The present invention relates to methods for substantially enhancing the stereoselective synthesis of .beta.-anomeric nucleoside analogs. In methods according to the present invention, the introduction of a phenylseleno group onto a blocked lactone sugar precursor may be selected so that the desirable phenylseleno substituent is introduced on the side of the blocked lactone away from the blocking group. This stereospecific introduction of the phenylseleno group in sugar precursor allows the synthesis of nucleoside analogs and in particular, 2',3',-dideoxy- and 2',3'-dideoxy-2',3'-didehydronucleoside analogs in very high yield. In certain preferred embodiments, the preferred phenylseleno blocked lactone is obtained in an amount representing approximately 90% or more of the total amount of the stereoisomers obtained. In even more preferred embodiments, the amount of the preferred stereoisomer is at least 95%, even more preferably at least about 97% of the total amount of phenylseleno blocked lactone produced.

  • Patent number: 6002026
    Abstract: The present invention relates to novel oxidative processes for substrates such as olefins, alkanes, aromatics and alcohols using metallic porphyrin or salen catalytic complexes which have been specifically designed to maximize catalytic activity, thereby enhancing efficiency, selectively and speed of oxidation of these substrates. The choice of the substituents in the metallic complexes may be varied, but must be chosen to prevent specific ligand set arrangements known to be stable and therefore less catalytically efficient. Coordination complexes, particularly porphyrins and salens having nitrosyl axial ligands and electron-withdrawing peripheral substituents are preferred. Ruthenium coordination metals are the preferred metal center, with the highly reactive catalytic species found to be Ru.sup.III.
