O-Alkylation of Cupferron:  Aiming at the Design and Synthesis of Controlled Nitric Oxide Releasing Agents

, 2016
O-Alkylation of N-nitroso-N-phenylhydroxylamine ammonium salt (cupferron) was studied for the synthesis of novel nitric oxide (NO) releasing agents. The alkylation occurred regioselectively at the terminal oxygen, leading to a single product N-(alkyloxy)-
