摘要:
Oligonucleotide analogs are disclosed having pyrimidine monomeric sub-units therein that are modified at the 2′ and 5′ positions. Monomeric sub-units having these modifications may be further modified at the 2′ position. Improved processes for the synthesis of 2′-O-substituted pyrimidine nucleosides are also provided. The processes feature alkylation of a 2,2′-anhydropyrimidine nucleoside or a 2S,2′-anhydropyrimidine nucleoside with a weak nucleophile in the presence of a Lewis acid.

摘要:
The present invention provides monocyclic, bicyclic and oligomeric amine compounds with at least two sites of diversity. These compounds are formed from monocyclic scaffolds which can be cyclized to form bicyclic amine scaffolds. These can then be reacted with building blocks to form the amine compounds of the invention. This invention further provides libraries or monocyclic, bicyclic and oligomeric amine compounds. Also provided are methods for preparing monocyclic, bicyclic and oligomeric amine compounds and libraries thereof. The present invention also provides pharmaceutical compositions of the monocyclic, bicyclic and oligomeric amine compounds.
