Scheme 3. Overview of the Reaction Scope of cPyPA and Analoguesa.

Scheme 3.

a[a] The triphosphates were directly precipitated from the reaction mixture by using NaClO4 in acetone without further purification. [b] The reaction mixture was characterized by NMR, and the product was directly used for the next transformations. [c] The product was precipitated from the reaction mixture and purified by anion exchange chromatography (SAX). [d] The product was precipitated from the reaction mixture and subsequently purified by Reverse Phase MPLC.
