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:Provided herein are improved methods for the synthesis of reactive conjugate clusters and intermediates used in such methods. In particular, improvements are provided that enhance the synthesis of reactive conjugate clusters by reducing the number of synthetic steps required. The reactive conjugate clusters prepared using the improved methods don't include any transacylation impurities that are formed using existing methods. The improved methods also provide an increase in overall yield and a cost benefit over existing methods.
