Design of a new oligotriazole peptide nucleic acid analogue (oT-PNA)
摘要:
We describe in this Letter the synthesis of an original thymine azido-heterotrimer generated by Click Chemistry. This trimer has been obtained from an azido-thymidine and a new chloroethyl-propargylated PNA monomer analogue, after two azidation/click-reaction cycles. Conformational preferences of a rotameric intermediate have also been studied (C) 2011 Elsevier Ltd. All rights reserved.

An efficientsynthesis of siRNAs modified at the backbone with a triazole functionality is reported. Through the use of 4,4′-dimethoxytrityl (DMT) phosphoramidite chemistry, triazole backbone dimers were site-specifically incorporated throughout various siRNAs targeting both firefly luciferase and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) gene transcripts as representatives of an exogenous and

This letter extends the scope of the rhodium(I)-catalyzedallenic Alder-ene carbocyclization reaction to the preparation of delta- and epsilon-lactams from amides. A variety of allenic propiolamides were cycloisomerized to give a number of unsaturated delta-lactams. In addition, allenic propargylamides give good yields of the corresponding epsilon-lactams. Formation of lactams possessing these ring

needed to improve the properties of oligonucleotides. A practical synthesis for a triazole‐linked nucleoside dimer based on a PNA‐like structure has been developed. This involves synthesizing two uracil‐based monomers that contain either an azide or an alkyne functionality, followed by copper‐catalyzed 1,3‐dipolar cycloaddition. This dimer was incorporated within an oligonucleotide via phosphoramidite

Here we report a modular two-step synthesis of cyclic β-fluoroalkyl amines using a photoredox-catalysed cyclisation/hydrogen atom transfer reaction of bromodifluoroethylamines.
