Abstract
The structural puzzle of amipurimycin, a peptidyl nucleoside antibiotic, is solved by total synthesis and X-ray diffraction analysis, with the originally proposed configurations at C3' and C8' inverted and those at C6', C2'', and C3'' corrected. A similar structural revision of the relevant miharamycins is proposed via chemical transformations and then validated by X-ray diffraction analysis. The miharamycins bear an unusual trans-fused dioxabicyclo[4.3.0]nonane sugar scaffold, which was previously assigned as being in the cis configuration.

Abstract
Two α-L-ribo-configured bicyclic nucleic acid modifications, represented by analogues 12 and 13, which are epimeric at C3' and C5' have been synthesized using a carbohydrate-based approach to build the bicyclic core structure. An intramolecular L-proline-mediated aldol reaction was employed to generate the cis-configured ring junction of analogue 12 and represents a rare application of this venerable organocatalytic reaction to a carbohydrate system. In the case of analogue 13, where a trans-ring junction was desired, an intermolecular diastereoselective Grignard reaction followed by ring-closing metathesis was used. In order to set the desired stereochemistry at the C5' positions of both nucleoside targets, a study of diastereoselective Lewis acid mediated allylation reactions on a common bicyclic aldehyde precursor was carried out. Analogue 12 was incorporated in oligonucleotide sequences, and thermal denaturation experiments indicate that it is destabilizing when paired with complementary DNA and RNA. However, this construct shows a significant improvement in nuclease stability relative to a DNA oligonucleotide.

Abstract
Two bicyclic 2'-deoxynucleoside analogues are synthesized in 12 steps each from thymidine. With a six-membered ring fused to the C3'-C4' bond and an alpha-L-ribo- and a beta-D-xylo-configuration, these are conformationally restricted in an S- and an N-type conformation, respectively. The constitutions were proven by X-ray crystallography. The beta-D-xylo-configured analogue is successfully converted to a 3'-phosphoramidite and incorporated into oligodeoxynucleotides, which are found to hybridize to DNA and RNA complements with decreased affinity.

Abstract
1,6-Dihydro-3(2H)-pyridinone, designed as a common synthon for synthesis of various natural products, was found to be easily prepared in large scale and successfully used to synthesize a variety of alkaloids such as ibogamine, quinine and tecomanine. A tricyclo[3.3.0.0(2.8)]octane was also served as a common synthon for several sesquiterpenes such as pentalenene and quadrone. Synthetic studies by using sulfinyl chirality via an intramolecular Michael addition gave the novel route to construct spiro-ketal moiety in enantiomerically pure form. By applying this method, many natural spiro-ketal compounds were asymmetrically synthesized effectively. 3-Sulfinylated 1,4-dihydropyridine, a chiral NADH model compound, reduced activated ketones such as methyl benzoylformate to give the corresponding alcohols in excellent optical yields. A kind of 3-O-substituted pyridoxal chiral model compound was useful for preparation of alpha,alpha-dialkylated alpha-amino acids by asymmetric alpha-alkylation of alpha-amino acids. 2'-O,4'-C-Bridged nucleic acid analogs, BNAs, developed as novel type of artificial nucleic acids, showed an extraordinarily high binding affinity toward single stranded RNA and double stranded DNA complements along with excellent nuclease-resistant ability. Oligonucleotides containing BNA monomer units were proved to be very useful for various biotechnologies, such as antisense and antigene methodologies.

Abstract
Recently, we synthesized pyrimidine derivatives of the 2'-O,4'-C-methylenoxymethylene-bridged nucleic-acid (2',4'-BNA(COC)) monomer, the sugar conformation of which is restricted in N-type conformation by a seven-membered bridged structure. Oligonucleotides (BNA(COC)) containing this monomer show high affinity with complementary single-stranded RNA and significant resistance to nuclease degradation. Here, BNA(COC) consisting of 2',4'-BNA(COC) monomers bearing all four bases, namely thymine, 5-methylcytosine, adenine and guanine was efficiently synthesized and properties of duplexes containing the 2',4'-BNA(COC) monomers were investigated by UV melting experiments and circular dichroism (CD) spectroscopy. The UV melting curve analyses showed that the BNA(COC)/BNA(COC) duplex possessed excellent thermal stability and that the BNA(COC) increased thermal stability with a complementary RNA strand. On the other hand, BNA(COC)/DNA heteroduplexes showed almost the same thermal stability as RNA/DNA heteroduplexes. Furthermore, mismatched sequence studies showed that BNA(COC) generally improved the sequence selectivity with Watson-Crick base-pairing compared to the corresponding natural DNA and RNA. A CD spectroscopic analysis indicated that the BNA(COC) formed duplexes with complementary DNA and RNA in a manner similar to natural RNA.
