As a common heterocyclic compound, it belongs to chiral-nitrogen-ligands compound, name is N1,N2-Dimethylethane-1,2-diamine, and cas is 110-70-3, its synthesis route is as follows.,110-70-3
EXAMPLE 12 N-Boc-N,N’-dimethylethylene diamine N,N’-dimethyl ethylenediamine (8.8 g) was dissolved in 200 ml tetrahydrofuran and to this was added over a 10 min period di-t-butyldicarbonate (4.36 g) in 30 mL tetrahydrofuran. 72 hours later, the solvent was evaporated and the residue partitioned between ether and KHCO3 and the organic layer was dried (MgSO4) and evaporated to give 11.6 g title compound (58% yield). 300 MHz 1 H NMR was consistent with proposed structure.
110-70-3 is used more and more widely, we look forward to future research findings about N1,N2-Dimethylethane-1,2-diamine
