Li, Kaiqi; Chen, Long; Xiong, Zuochun; Xiong, Chengdong; Chen, Dongliang published an article in 2022. The article was titled 《New aliphatic poly(ester-carbonate)s bearing amino groups based on t-Butyloxy carbonyl as Protecting Group》, and you may find the article in Journal of Polymer Research.Name: 2-Aminopropane-1,3-diol The information in the text is summarized as follows:
Amino-functionalized six-membered cyclic carbonate tert-butyl(2-oxo-1,3-dioxan-5′-yl) carbamate (TBC) was synthesized with tert-Butyloxycarbonyl (Boc) as protected group. Due to its thermal properties, ring-opening polymerization (ROP) carried out in a relatively low temperature, and Sn (Oct)2 as catalyst. A series of copolymers were prepared with L-lactide (LA), ε-Caprolactone (CL) as co-monomers, searching for proper components and ratios. The protecting Boc-group was easy to remove by using trifluoroacetic acid (TFA). The structures of TBC and copolymers were confirmed by 1H NMR and 13C NMR anal. Copolymers were characterized by DSC, GPC and water contact angle anal. The introduction of pendant amino groups resulted in a significant enhancement of hydrophilicity of the copolymers. The experimental part of the paper was very detailed, including the reaction process of 2-Aminopropane-1,3-diol(cas: 534-03-2Name: 2-Aminopropane-1,3-diol)
2-Aminopropane-1,3-diol(cas: 534-03-2) belongs to anime. Milder oxidation, using reagents such as NaOCl, can remove four hydrogen atoms from primary amines of the type RCH2NH2 to form nitriles (R―C≡N), and oxidation with reagents such as MnO2 can remove two hydrogen atoms from secondary amines (R2CH―NHR′) to form imines (R2C=NR′). Tertiary amines can be oxidized to enamines (R2C=CHNR2) by a variety of reagents.Name: 2-Aminopropane-1,3-diol
