Herein we describe a method to orthogonally remove on-DNA N-Cbz, N-Alloc, N-Allyl, O-Bn, and O-Allyl protecting groups in the presence of other common protecting groups to afford free amines and carboxylic acids, resp. The developed method uses NaBH4 as the source of hydrogen in the presence of Pd(OAc)2 under DNA aqueous conditions. In addition, under the developed conditions we were able to successfully hydrogenate triple and double bonds to totally saturated compounds Furthermore, we introduce a new alternative procedure to reduce azides and aromatic nitro compounds to primary amines. In the experiment, the researchers used many compounds, for example, 4-((Benzyloxy)carbonyl)-1-(tert-butoxycarbonyl)piperazine-2-carboxylic acid (cas: 149057-19-2Safety of 4-((Benzyloxy)carbonyl)-1-(tert-butoxycarbonyl)piperazine-2-carboxylic acid).
4-((Benzyloxy)carbonyl)-1-(tert-butoxycarbonyl)piperazine-2-carboxylic acid (cas: 149057-19-2) belongs to piperazine derivatives. The piperazine scaffold is often found in biologically active compounds in different therapeutic areas. These therapeutic areas include antifungals, antidepressants, antivirals, and serotonin receptor (5-HT) antagonists/agonists. Piperazine is an anthelminthic especially useful in the treatment of partial intestinal obstruction caused by Ascaris worms, which is a condition primarily seen in children. Piperazine hydrate and piperazine citrate are the main anthelminthic piperazines.Safety of 4-((Benzyloxy)carbonyl)-1-(tert-butoxycarbonyl)piperazine-2-carboxylic acid
