A new silver-free synthesis for cyclooctynol is introduced. The obtained alcohol was further functionalized by a Mitsunobu reaction to give an assortment of imide and phenol derivatives. It was also possible to further functionalize the cyclooctyne by treatment with a fluorescein dye. As an interesting application, we used a cyclooctyne-maleimide conjugate as an azide-thiol crosslinker.
