A facile preparation of functional cycloalkynes via an azide-to-cycloalkyne switching approach

Abstract

A facile method for preparing various functional cycloalkynes, including proteins installed with a cycloalkyne moiety, from corresponding azides is developed. Treatment of diynes bearing strained and terminal alkyne moieties with a copper salt enabled the terminal alkyne-selective click conjugation with azides, whereas a more azidophilic strained alkyne moiety was transiently protected from click reaction by complexation with copper.
