Abstract
A convenient synthetic route to 1,4-bis(tert-butoxycarbonylmethyl)tetraazacyclododecane (cyclen) (1) with high yield and excellent regioselectivity is described. Compound 1 reacted with a range of functionalized alkyl halides under two reaction conditions to give mono-N-alkylated 1,4-bis(tert-butoxycarbonylmethyl)tetraazacyclododecane (2-9) in good yield.
