Synthesis of ferrocene-labeled steroids via copper-catalyzed azide–alkyne cycloaddition. Reactivity difference between 2β-, 6β- and 16β-azido-androstanes

[Display omitted] ► New ferrocene labeled steroidal triazoles were produced. ► Products were obtained by a cycloadditon of steroidal azides with ferrocenyl alkynes. ► A great difference in the reactivity of 6β- and 2β-/16β-azido–androstanes was observed. ► The same difference was observed in the cyc...
