Primary amine diazeniumdiolate ions of structure {RNN(O)NOR′}− as ambident nucleophiles
摘要:
An O-2-substituted primary amine diazeniumdiolate RHN-N(O)=NOR' is ionized to an anion that attacks an electrophile R '' X via either of two nitrogens to form both RR '' N-N(O)=NOR' and R-N=N(O)-N(R '')OR'. The bidentate character of such anions should be kept in mind when planning or evaluating drug discovery efforts involving diazeniumdiolates of structure RHN-N(O)=NOR'. (C) 2009 Elsevier Ltd.
