title: o-nitrobenzenesulfonamides in nucleoside synthesis: efficient 5'-aziridination of adenosine.
abstract: 5'-Aziridinoadenylates of the form 1 and a related nitrogen mustard variant have been constructed using a novel variation of the Mitsunobu reaction. Such molecules allow conversion of biological methyltransferases into nucleoside transferases, thus providing powerful tools for investigating S-adenosyl-l-methionine (SAM)-dependent methylation. We present here a highly effective synthesis of such molecules that is amenable to aziridine diversification as well as elaboration of the base moiety so as to afford "bumped" cofactor mimics compatible with "hole"-bearing mutant proteins.
