Reduction of 2'-deoxy-2'-hydroxyiminouridine derivatives led to a "first generation" hydroxylamine (2'-deoxy-2'-hydroxyaminouridine 8, mostly arabino configuration) which on treatment with aldehydes afforded the corresponding nitrones 9 which were reduced to "second generation" hydroxylamines 12.The modified nucleosides bearing a hydroxylamino group at the 2'-position, when of arabino configuration underwent conjugate addition onto the uracil ring leading to novel types of cyclonucleosides (3,5,10,13).
