2,2-Dimethyl-2-(o-nitrophenyl)acetyl (DMNA) as an assisted cleavage protecting group for amines

Jiang, Yongying,Zhao, Jun,Hu, Longqin

, p. 4589 - 4592 (2002)

2,2-Dimethyl-2-(o-nitrophenyl)acetyl group (DMNA) was explored as an assisted cleavage protecting group for amines and a one-step deprotection condition was developed for its efficient removal using hydrogenation in the presence of Pd-C or PtO2 catalyst and 10% HOAc in MeOH. DMNA was found to be especially useful for the synthesis of gem-diamino compounds using Hofmann rearrangement.
