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.

Abstract A two-step synthesis of methyl (E)-5-nitro-2-pentenoate involving addition of nitrous acid to acrolein followed by Wittig olefination is described. The preparation can be routinely carried out on a 0.1 mole scale to afford the title compound in 45–50% overall yield as a 92:8 mixture of the E:Z double bond isomers.
Abstract Two different organocatalytic approaches for the asymmetricsynthesis of 2,3,4-trisubstituted piperidines were developed. Both approaches were based on an aza-Michael addition followed by cyclization and gave products in high enantiomeric excess. Two different organocatalytic approaches for the asymmetricsynthesis of 2,3,4-trisubstituted piperidines were developed. Both approaches were based

Reactions with Ac2O/Py of sodium nitronate salts derived from primary or secondary nitroalkanes bearing hydroxyl groups at γ or more remote positions have been studied. In all cases, the results could be explained through an acetic nitronic anhydride intermediate, whose evolution depends on conformational factors, and also on the type of the hydroxyl group.
已经研究了由γ或更远的位置带有羟基的伯或仲硝基烷烃衍生的亚硝酸钠盐与Ac 2 O / Py的反应。在所有情况下,结果都可以通过乙酸乙酸酐中间体来解释,该中间体的演变取决于构象因素,还取决于羟基的类型。
