标题:Method for synthesis of linkage modified oligomeric compounds
发明人：RODRIGUEZ ANDREW A
权利人:IONIS PHARMACEUTICALS INC
摘要:The present disclosure provides methods of synthesizing modified oligonucletodies and oligomeric compounds (including oligomeric compounds that are antisense agents or portions thereof) comprising a modified oligonucleotide having at least one modified internucleoside linking group. In certain embodiments, the present disclosure provides stabilized formulations of certain sulfonyl azides for use in the synthesis of olignonucleotides comprising one or more sulfonyl phosphoramidate linkages. Some embodiments provide stabilized compositions of high energy reagents that may be used in the synthesis of modified oligonucleotides, allowing for safe process scale preparation thereof.

摘要:The present invention provides unified synthesis of the C1-C19 building blocks of halichondrins and analogs thereof using selective coupling of poly-halogenated nucleophiles in chromium-mediated coupling reactions. The present invention also provides a practical and efficient synthesis of C20-C38 building blocks of halichondrins and analogs thereof. Also provided herein are general methods of selective activation and coupling of poly-halogenated analogs with an aldehyde. The provided coupling reactions are selective for halo-enone and halo-acetylenic ketal over vinyl halide and halide attached to a sp hybridized carbon. The provided efficient selective coupling reactions can allow easy access to the C1-C19 building blocks and C20-C38 building blocks of halichondrins and analogs thereof with limited or no purification or separation of the intermediates.
