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.

权利人:SIERZCHALA AGNIESZKA B; SMART BRIAN PHILLIP; DELLINGER DOUGLAS J; DELLINGER GERALDINE; MYERSON JOEL; TIMAR ZOLTAN; AGILENT TECHNOLOGIES INC
摘要:A nucleoside monomer that is protected by a thionocarbamate protecting group and contains one or more 2 H, 13 C, or 15 N isotopes in the ribose and/or base part is provided, as well as a method for making a polynucleotide that uses the same. Also provided is a polynucleotide synthesis method that employs a diamine to deprotect a protected polynucleotide.
