ABSTRACT
A novel and efficient way for the synthesis of N6 -hydantoin-modified adenosines, which utilizes readily available N6 -(N-Boc-α-aminoacyl)-adenosine derivatives, was developed. The procedure is based on the epimerization-free, Tf2 O-mediated conversion of the Boc group into an isocyanate moiety, followed by intramolecular cyclization. Using this method two recently discovered hydantoin modified tRNA adenosines, that is, cyclic N6 -threonylcarbamoyl-adenosine (ct6 A) and 2-methylthio-N6 -threonylcarbamoyladenosine (ms2 ct6 A) were prepared in good yields.
