摘要
Conditions for facile solution-phase amide conjugation of amine-modified siRNA with a diverse set of carboxylic acid partners using the coupling reagent HATU are described. These conditions eliminate the need for isolated activated esters and allow for rapid access to conjugates with a wide range of lipophilicity and functionality in good yield.
