(2R,4S)-Boc-D-Pro(4-N3)-OH

(2R,4S)-Boc-D-Pro(4-N3)-OH is a click chemistry reagent containing an azide[1]. (2R,4S)-Boc-D-Pro(4-N3)-OH is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. Strain-promoted alkyne-azide cycloaddition (SPAAC) can also occur with molecules containing DBCO or BCN groups.
