The present invention relates to oligomer compounds, including dimers and trimers, formed by a disulfide, sulfinyl thio, olefin or hydrocarbon bond, or a hydrazone exchange bond between two or more monomers. Methods of making the monomers and the oligomers is also disclosed. Use of the compounds for inhibiting the activity of target RNA molecules, particularly those having a secondary structure that include a stem or stem-loop formation. Dimer compounds capable of inhibiting the activity of an HIV-1 RNA frameshifting stem-loop and a (CUG)n expanded repeat stem- loop are disclosed, as are methods of treating diseases associated with these target RNA molecules.
When the PADAM (Passerini reaction-amine deprotection-acyl migration) strategy is applied to N-Boc amino acids, the resulting β-acylamino-α-hydroxyamides can be elaborated by secondary-alcohol oxidation, Boc deprotection, and intramolecular cyclisation. When TFA is employed to cleave the Boc group a spontaneous aromatisation to 2(1H)-pyrazinones is observed.
9‐Helix: 4‐Amino(methyl)‐1,3‐thiazole‐5‐carboxylic acids (ATCs) were synthesized as new γ‐amino acid building blocks. The structures of various ATC oligomers were analyzed in solution by CD and NMR spectroscopy and in the solid state by X‐ray crystallography. The ATC sequences adopted a well‐defined 9‐helix structure in the solid state and in aprotic and protic organic solvents as well as in aqueous

oxidation of primary alcohols and beta-amino alcohols to the corresponding aldehydes and alpha-amino aldehydes can be carried out at room temperature and in methylene chloride, using trichloroisocyanuric acid in the presence of catalytic TEMPO: aliphatic, benzylic, and allylic alcohols, and beta-amino alcohols are rapidly oxidized without no overoxidation to carboxylic acids. Secondary carbinols are slowly
