    摘要: Methods for the alkylation of alcohols, amines and thiols by the use of cyclic sulfates are disclosed. The alkylated sulfates formed are versatile intermediates which may be further elaborated by methods of the invention. In particular, methods for the alkylation of the 2′, 3′ or 5′-hydroxy position of nucleosides and nucleoside analogs with cyclic sulfates to form the 2′, 3′ or 5′-O-alkyl sulfate modified compounds are disclosed. Displacement of the 2′,3′ or 5′-O-sulfate with a nucleophile provides 2′, 3′ or 5′-O-modified nucleosides and nucleoside analogs useful for the synthesis of oligomeric compounds having improved hybridization affinity and nuclease resistance.

    摘要: Novel macrocyclic compounds are constructed to include a ring or ring system having two bridgehead atoms with a bridge extending between the bridgehead atoms. Located in at least the bridge are two or more nitrogenous moieties that are derivatized with chemical functional groups. The ring or ring systems can include further nitrogenous moieties, either as ring atoms or on pendant groups attached to the ring. These can also be derivatized with chemical functional groups. The totality of the chemical functional groups imparts certain conformational and other properties to the compounds. In accordance with certain embodiments of the invention, libraries of such compounds are prepared utilizing permutations and combinations of the chemical functional groups and the nitrogenous moieties to build complexity into the library.

    摘要: Novel macrocyclic compounds are constructed to include large cyclic structures that are interrupted by at least one ring system. Each interrupting ring system includes two bridgehead atoms. Bridgehead atoms are bonded to one or more bridges that interconnect one or more ring systems thereby forming a large cyclic structure. Located in each bridge are two or more nitrogenous moieties that are derivatized with chemical functional groups. The ring systems can include further nitrogenous moieties, either as ring atoms or on pendant groups attached to the ring. These can also be derivatized with chemical functional groups. The totality of the chemical functional groups imparts certain conformational and other properties to the macrocyclic compounds. In accordance with certain embodiments of the invention, libraries of such macrocyclic compounds are prepared utilizing permutations and combinations of the chemical functional groups and the nitrogenous moieties to build complexity into the library.
