Abstract
A complete series of the 2 '-5 ' and 3 '-5 ' regioisomeric types of r(ApA) and 2 '-d(ApA) analogues with the α-hydroxy-phosphonate C3 '-O-P-CH(OH)-C4 ″ internucleotide linkage, isopolar but non-isosteric with the phosphodiester one, were synthesized and their hybridization properties with polyU studied. Due to the chirality on the 5 '-carbon atom of the modified internucleotide linkage bearing phosphorus and hydroxy moieties, each regioisomeric type of ApA dimer is split into epimeric pairs. To examine the role of the 5 '-hydroxyl of the α-hydroxy-phosphonate moiety during hybridization, the appropriate r(ApA) analogues with 3 '(2 ')-O-P-CH(2)-C4 ″ linkage lacking the 5 '-hydroxyl were synthesized. Nuclear magnetic resonance (NMR) spectroscopy study on the conformation of the modified sugar-phosphate backbone, along with the hybridization measurements, revealed remarkable differences in the stability of complexes with polyU, depending on the 5 '-carbon atom configuration. Potential usefulness of the α-hydroxy-phosphonate linkage in modified oligoribonucleotides is discussed.

Abstract
Modified internucleotide linkage featuring the C3'-O-P-CH(2)-O-C4'' phosphonate grouping as an isosteric alternative to the phosphodiester C3'-O-P-O-CH(2)-C4'' bond was studied in order to learn more on its stereochemical arrangement, which we showed earlier to be of prime importance for the properties of the respective oligonucleotide analogues. Two approaches were pursued: First, the attempt to prepare the model dinucleoside phosphonate with (13)C-labeled CH(2) group present in the modified internucleotide linkage that would allow for a more detailed evaluation of the linkage conformation by NMR spectroscopy. Second, the use of ab initio calculations along with molecular dynamics (MD) simulations in order to observe the most populated conformations and specify main structural elements governing the conformational preferences. To deal with the former aim, a novel synthesis of key labeled reagent (CH(3)O)(2)P(O)(13)CH(2)OH for dimer preparation had to be elaborated using aqueous (13)C-formaldehyde. The results from both approaches were compared and found consistent.

Abstract
We have synthesized diastereomerically pure diadenosine 3',5'-boranophosphates (Ap(b)A) by using the boranophosphotriester method from ribonucleosides protected with the 2'-hydroxy protecting group 2-cyanoethoxymethyl (CEM). Melting curves of the triple-helical complex of the dimer Ap(b)A and 2poly(U) at high ionic strength revealed that presumptive (Sp)-Ap(b)A had a much higher affinity and presumptive (Rp)-Ap(b)A a much lower affinity for poly(U) than the natural dimer ApA did. In contrast, the affinities of these dimers for poly(dT) were similar. Both the (Rp)- and the (Sp)-boranophosphate diastereomers showed much higher resistance to digestion by snake venom phosphodiesterase and nuclease P1 than ApA did. They have potential for use as synthons to be incorporated into boranophosphate oligonucleotides. In particular, because oligonucleotides containing Sp boranophosphate nucleotides are expected to bind more strongly and specifically to RNA than natural oligoribonucleotides do, they may find application in the isolation and detection of functional RNA in basic research and diagnostics.

Abstract
A synthetic approach leading to novel-type modified oligothymidylates containing an isosteric, isopolar, enzyme-stable C3'-O-P-CH(2)-O-C4'' phosphonate alternative to phosphodiester internucleotide bond was elaborated. The suitable monomers were prepared from 4'-phosphonomethoxy derivatives of alpha-L-threo and beta-D-erythro-2',5'-dideoxythymidine, which were considered interesting as structurally related to nucleoside 5'-monophosphates. The phosphotriester method was applied to the automated synthesis of both homooligomeric phosphonate 15-mer chains and alternating phosphonate-phosphate constructs. The fully modified homooligomers did not hybridize while homooligomers with alternating sequences containing alpha-L-threo-configured units (but not beta-D-erythro-) showed a significant decrease in T(m) values in comparison with natural dT(15). For a comparative study, phosphodiester 4'-CH(3)-substituted oligothymidylate was synthesized and physical studies (NMR, CD, MDS modeling) were undertaken to shed more light on the changes in conformational behavior arising from the chosen structural alterations.

Abstract
En route to conformationally restricted analogues of nicotine and anabasine, a novel synthetic route to bridged anabasines is described that hinges on a domino intramolecular [4 + 2]-cycloaddition/ring opening-elimination sequence of 3-amino-substituted furo[3,4-c]pyridines. Extension of this route to bridged nicotines, however, proved abortive, even when the dienophile tether is activated by a p-tolylsulfonyl group or when the diene moiety is activated by an electron-releasing methoxy substituent. A detailed density functional theoretical study (B3LYP/6-31+G) was undertaken to provide insight into the factors that facilitate an intramolecular Diels-Alder reaction in the former case.

Abstract
The complete family of ApA phosphonate analogues with the internucleotide linkage elongated by insertion of a -CH2- group was prepared and the hybridisation and structural properties of its members in interaction with polyuridylic acid were investigated using an original 2D Raman approach. Except for the conformationally restricted A(CH)pA(2'3'endo-5') modification, all of the isopolar, non-isosteric analogues form triplex-like complexes with poly(rU) at room temperature, in which two polymer strands are bound by Watson-Crick and Hoogsteen bonds to a central pseudostrand consisting of a 'chain' of A-dimers. For all of these dimers, the overall conformation of the triplexes was found to be similar according to their extracted Raman spectra. A simple semi-empirical model was introduced to explain the observed dependency of the efficiency of triplex formation on the adenine concentration. Apparently, for most of the modifications studied, the creation of a stable complex at room temperature requires the formation of a central pseudostrand, consisting of several adenine dimers. Molecular dynamics calculations were finally performed to interpret the differences in 'cooperative' behaviour between the different dimers studied. The results indicate that the exceptional properties of the Ap(CH2)A(3'-5') dimer could be caused by the 3D conformational compatibility of this modified linkage with the second (Hoogsteen) poly(rU) strand.
