  The present invention provides bicyclic morpholino compounds and oligomeric compounds prepared therefrom. More particularly, incorporation of one or more of the bicyclic morpholino compounds into an oligomeric compound is expected to enhance one or more properties of the oligomeric compound. Such oligomeric compounds can also be included in a double stranded composition. In certain embodiments, the oligomeric compounds provided herein are expected to hybridize to a portion of a target RNA resulting in loss of normal function of the target RNA.

• Synthesis and Biophysical Evaluation of 2′,4′-Constrained 2′<i>O</i>-Methoxyethyl and 2′,4′-Constrained 2′<i>O</i>-Ethyl Nucleic Acid Analogues

  We have recently shown that combining the structural elements of 2'O-methoxyethyl (MOE) and locked nuclecic acid (LNA) nucleosides yielded a series of nucleoside modification (cMOE, 2',4'-constrained MOE; cEt, 2',4'-constrained ethyl) that display improved potency over MOE and an improved therapeutic index relative to that of LNA antisense oligonucleotides. In this report we present details regarding the synthesis of the cMOE and cEt nucleoside phosphoramidites and the biophysical evaluation of oligonucleotides containing these nucleoside modification. The synthesis of the cMOE and eEt nucleoside phosphoramidites was efficiently accomplished starting from inexpensive commercially available diacetone allofuranose. The synthesis features the use of a seldom used 2-naphthylmethyl protecting group that provides crystalline intermediates during the synthesis and can be cleanly deprotected under mild conditions. The synthesis was greatly facilitated by the crystallinity of a key mono-TBDPS-protected diol intermediate. In the case of the cEt nucleosides, the introduction of the methyl group in either configuration was accomplished in a stereoselective manner. Ring closure of the 2'-hydroxyl group onto a secondary mesylate leaving group with clean inversion of stereochemistry was achieved under suprisingly mild conditions. For the S-cEt modification, the synthesis of all four (thymine, 5-methylcytosine, adenine, and guanine) nucleobase-modified phosphoramidites was accomplished on a multigram scale. Biophysical evaluation of the cMOE- and cEt-containing oligonucletides revealed that they possess hybridization and mismatch discrimination attributes similar to those of LNA but greatly improved resistance to exonuclease digestion.
