摘要:The present invention provides methods for the synthesis of ketones involving a Ni/Zr-mediated coupling reaction. The Ni/Zr-mediated ketolization reactions can be used in the synthesis of halichondrins (e.g., halichondrin A, B, C; homohalichondrin A, B, C; norhalichondrin A, B, C), and analogs thereof. Therefore, the present invention also provides synthetic methods useful for the synthesis of halichondrins, and analogs thereof. Also provided herein are compounds (i.e., intermediates) useful in the synthesis of halichondrins, and analogs thereof. In particular, the present invention provides methods and compounds useful in the synthesis of compound of Formula (H3-A).

标题:Synthesis of oligonucleotides and related compounds

摘要:Methods of synthesizing oligonucleotides via new intermediates on a cleavable support having an azidomethyl moiety are disclosed. The method comprises multiple reaction cycles, each of which comprises sequential coupling a nucleoside or oligonucleotide subunit on a cleavable support having an azidomethyl moiety and a nucleoside phosphoramidite or an oligonucleotide phosphoramidite, capping, oxidation/thiolation and deblocking; followed by orthogonal cleavage of the azidomethyl support while keeping all other protecting groups intact. The method can be used in combination with a support moiety for either solid phase or liquid phase oligo synthesis. The soluble support facilitates homogeneous reactions and efficient separations by simple precipitation. The methods also provide novel intermediates useful in the synthesis of oligonucleotide conjugates.

摘要:The present invention relates to a 1,1-diborylalkyl-1-metal compound including one metal group together with two identical boron groups at the sp3 carbon center, and its use. Specifically, the present invention relates to development of novel organic reactions, synthesis of functional molecules, and synthesis of new drugs by applying the novel 1,1-diboryl-1-metal substituted alkyl compounds to various molecular libraries which could not be synthesized by conventional methodologies.

摘要:A process for the chemical synthesis of oligonucleotides n Use of a dansylethoxycarbonyl group as base-labile 5'-hydroxyl protective group in the chemical synthesis of DNA and RNA and suitable synthetic processes. n The ease of detection of the dansyl protective group and the ease of elimination from the sugar residue of the nucleotide without side reactions make oligonucleotide synthesis possible with high yields in very small quantities.
