The invention aims in establishing a method for modifying biomolecules using a reaction that efficiently modifies biomolecules and is widely applicable. The invention thus provides a cyclic compound containing two triazole rings formed by adding and ligating an azide compound possessing an azido group to each of the two carbon-carbon triple bond sites of an eight-membered cyclic skeleton of a cyclic diyne compound by a double click reaction; a method for producing a cyclic compound using a double click reaction; and a method for modifying biomolecules.
